How to Watch Underground Fights: The Complete Streaming Guide

There has never been a better time to be a fan of underground fighting. A decade ago, finding footage of backyard brawls, bare knuckle scraps, and unsanctioned MMA required digging through obscure forum links and hoping the video did not get pulled before you finished watching it. Today, the biggest underground fighting organizations in the world operate polished YouTube channels with millions of subscribers, sell pay-per-view events through dedicated platforms, and push daily content across every major social media network.

The challenge is no longer finding underground fights. The challenge is knowing where to look for the specific organization, event, or style you want to watch -- and understanding whether the content is free, pay-per-view, or locked behind a subscription. This guide breaks down every major platform and organization so you can start watching immediately.

YouTube: The Home Base for Underground Fighting

YouTube is, without question, the single most important platform in the underground fighting ecosystem. The vast majority of organizations use it as their primary distribution channel, and many upload full fights completely free of charge.

Streetbeefs

Streetbeefs is the largest backyard fighting channel on YouTube, with over 4 million subscribers and more than 1.4 billion total views across 3,600-plus videos. Virtually all of their content is available for free. You can watch full boxing, kickboxing, MMA, and grappling matches filmed at their outdoor venues in Virginia and at affiliated branches across the United States.

YouTube Channel: Search "Streetbeefs" -- the main channel features the Virginia-based events hosted by founder Chris "Scarface" Wilmore.
Content Type: Full fights, compilations, behind-the-scenes footage.
Cost: Free.
Upload Frequency: Multiple fights per week.

Streetbeefs also operates several branch channels, including Streetbeefs Scrapyard (the Gig Harbor, Washington affiliate run by Steve "Firechicken" Hagara), which uploads GoPro-filmed fight footage from their monthly events. The Scrapyard events are not open to spectators, so the YouTube channel is the only way to watch.

Top Dog Fighting Championship

Top Dog Fighting Championship is the largest bare knuckle promotion in Eastern Europe, based in Moscow. Their YouTube channel features full events with fights held in a ring made of hay bales. Fighters wear mouthguards and wrist wraps but no gloves, and bouts are won by knockout or decision.

YouTube Channel: Search "Top Dog Fighting Championship" -- content is primarily in Russian, though some videos include English subtitles.
Content Type: Full events, individual fight highlights, knockouts.
Cost: Free.
Upload Frequency: Regular event uploads, typically around 50-minute episodes.

Top Dog content also circulates heavily on TikTok, where knockout clips routinely rack up millions of views.

Strelka

Strelka is a Russian amateur MMA organization founded in 2011 in St. Petersburg. Their YouTube channel (now operating under the TronMMA brand) has surpassed one million subscribers and is one of the most-viewed fight channels on the platform. Strelka matches amateurs of approximately equal skill level and hosts outdoor fights across Russia.

YouTube Channel: Search "TronMMA" or "Strelka Street Fights."
Content Type: Full amateur MMA fights, compilations.
Cost: Free.
Upload Frequency: Regular uploads.

King of the Streets (KOTS)

King of the Streets is a European no-holds-barred fight promotion founded in 2013 in Sweden. Their YouTube channel has over one million subscribers and features some of the most intense vale tudo-style fighting available online.

YouTube Channel: Search "King of the Streets."
Content Type: Select full fights and highlight reels are free on YouTube. Full events are behind a paywall.
Cost: Free for selected content; full events are PPV (see below).
Upload Frequency: Fight clips and previews uploaded regularly between events.

Other Notable YouTube Channels

78sportstv: Known as "the King of Underground Boxing and MMA Talk," this channel covers the broader underground fighting scene with commentary, recaps, and interviews.
Backyard Squabbles: The Los Angeles-based fight organization uploads select clips and promotional content to YouTube, though their full events are distributed through TrillerTV.
Fight Hub TV: While not strictly underground, Fight Hub TV covers the crossover space between grassroots fighting and professional combat sports with interviews and event coverage.

Pay-Per-View Platforms

Several organizations have moved to a PPV model for their marquee events, reserving YouTube for promotional clips and older content.

Rough N Rowdy (BuyRnR.com)

Rough N Rowdy is Barstool Sports' amateur boxing PPV series, featuring untrained fighters in three-round bouts. Events are purchased and streamed exclusively through their website.

Platform: BuyRnR.com
Cost: $29.99 per event (includes live stream and one-week on-demand replay).
How It Works: Create a Barstool Sports account or log in with an existing one, purchase the event, and stream directly from the website player on any Chrome or Safari-compatible device.
TV Viewing: Mirror your device to a TV using Apple AirPlay or Chromecast.
YouTube: Rough N Rowdy also streams some events live on their YouTube channel and posts archived fights.

King of the Streets PPV

KOTS sells PPV access to their live events through their website at kingofthestreets.com. Their pricing operates in phases that reward early purchases:

Phase 1: Approximately 6 EUR
Phase 2: Approximately 10 EUR
Phase 3: Approximately 20 EUR
Day-of Price: Approximately 25 EUR

Buyers are typically notified of the event location and stream link just 24 hours before the event goes live. The secrecy surrounding event details is part of the KOTS brand and reflects the legal grey area in which the organization operates.

BKFC (Bare Knuckle Fighting Championship)

BKFC is the world's largest professional bare knuckle boxing promotion. While not underground in the traditional sense -- their events are fully sanctioned by state athletic commissions -- BKFC grew directly from the underground bare knuckle tradition and remains closely linked to the scene.

Platform: BKFC events are available through their app, their website, and various broadcast partners. Major events are available on PPV platforms and select content streams on YouTube.
Cost: Varies by event. Major cards like KnuckleMania are premium PPV, while smaller events may be included with a subscription or streamed on partner channels.
Free Content: BKFC posts fight highlights, knockouts, and promotional clips to their YouTube channel.

BKB (Bare Knuckle Boxing)

BKB is a UK-based bare knuckle boxing promotion. Their events are typically available through PPV on their website and through combat sports streaming platforms.

Backyard Squabbles (TrillerTV)

Backyard Squabbles, the Los Angeles-based fight organization with the "Guns Down, Squabble Up" ethos, distributes its full events through TrillerTV. You can find official replays and full fight cards on the platform.

Platform: TrillerTV
Social Media: Follow @backyardsquabbles on Instagram (30K+ followers) and TikTok (69K+ followers) for clips and event announcements.

Telegram Channels

Telegram has become an increasingly important distribution channel for underground fighting content, particularly for organizations that operate in legal grey areas or want to bypass the content moderation policies of mainstream platforms.

King of the Streets maintains an active Telegram channel where they post fight announcements, clips, and event updates. Search "King of the Streets" on Telegram.
Top Dog Fighting Championship and Strelka content is frequently shared through Russian-language Telegram channels dedicated to combat sports.
Various fan-run channels aggregate fight content from multiple organizations, though the quality and reliability of these channels varies widely.

A word of caution: Telegram channels are not moderated the same way YouTube or Instagram content is. You may encounter pirated content, misleading links, or channels that disappear without notice. Stick to official or verified channels whenever possible.

Social media platforms are primarily used for short-form content, event promotion, and community building rather than full fights. However, they are essential for staying up to date on upcoming events and catching highlight clips.

Instagram

Nearly every organization maintains an active Instagram presence. Key accounts to follow:

@streetbeefs -- Event announcements, fighter profiles, and behind-the-scenes content.
@topdogfight -- Top Dog Fighting Championship's official account with knockout clips and event promotion.
@backyardsquabbles -- Fight previews, event cards, and links to full events on TrillerTV.
@bareknucklefc -- BKFC's official account with over 2 million followers.

TikTok

TikTok has become a major driver of discovery for underground fighting. Short knockout clips, dramatic finishes, and walkout compilations go viral regularly, driving new viewers to YouTube channels and PPV platforms. Follow the official accounts of your preferred organizations, but also search hashtags like #undergroundfighting, #backyardfighting, #bareknuckle, and #streetfighting for fan-edited content.

X (Twitter)

@StreetBeefs -- News, event announcements, and fighter callouts.
@KOTSFightClub -- King of the Streets updates and event links.

Free vs. Paid Content: What You Get at Each Level

The majority of underground fighting content is available for free. Here is what you can expect without spending a dollar:

Full fights from Streetbeefs, Strelka, Top Dog, and select KOTS bouts.
Highlight reels and knockout compilations from virtually every organization.
Behind-the-scenes content, fighter interviews, and event previews.
Archived events that were originally PPV but have since been released for free.

Paid Content (PPV and Subscriptions)

Pay-per-view content typically offers:

Live event access -- watch fights as they happen, which is the main draw for dedicated fans.
Higher production quality -- PPV events from organizations like Rough N Rowdy and KOTS tend to have multiple camera angles, commentary, and professional-grade production.
Exclusive matchups -- the biggest fights and most anticipated rematches are often reserved for PPV cards.
On-demand replays -- most PPV purchases include a replay window (Rough N Rowdy offers one week).

How to Set Up Your Streaming Setup

If you want to watch underground fights on your TV rather than squinting at a phone screen, here are your best options:

Chromecast or Apple AirPlay: Most PPV platforms and YouTube support casting directly to your TV from a phone or laptop.
Smart TV YouTube App: The YouTube app on smart TVs, Roku, Fire Stick, and gaming consoles gives you direct access to all free fight content.
HDMI Cable: The simplest option. Connect your laptop to your TV and stream directly from any browser.
Browser on Smart TV: Some PPV platforms (like BuyRnR.com) work directly in a smart TV browser, though a laptop-to-TV connection is usually more reliable.

Staying Up to Date: Never Miss an Event

The underground fighting calendar does not follow the predictable scheduling of the UFC or professional boxing. Events are often announced weeks or even days in advance, and lineup changes are common. To stay on top of things:

Subscribe to YouTube channels with notifications turned on for your preferred organizations.
Follow official social media accounts on Instagram and TikTok.
Join Facebook groups -- Streetbeefs, The Scrapyard, and several other organizations use Facebook groups as their primary community hub and event announcement platform.
Check organization websites regularly. KOTS, BKFC, and Rough N Rowdy all list upcoming events on their official sites.
Join Telegram channels for organizations that use them.

The Bottom Line

The underground fighting world has never been more accessible. Between free YouTube content from organizations like Streetbeefs, Strelka, and Top Dog Fighting Championship, affordable PPV events from Rough N Rowdy and King of the Streets, and a constant stream of clips flowing through TikTok and Instagram, there is more content available than any one person could possibly consume.

Start with YouTube. Subscribe to the channels listed above. Follow the social media accounts. And when an event catches your eye, invest in a PPV -- it is the best way to support the organizations that keep this scene alive and growing.
