Darren Till scores brutal knockout in BKFC debut against Aaron Chalmers

Darren Till’s bare-knuckle debut ended in a violent statement, as the former UFC title challenger stopped Aaron Chalmers by second-round knockout after surviving an early knockdown at BKFC 90 in Birmingham, England.

The finish gave Bare Knuckle Fighting Championship exactly the kind of clip-driven spectacle it wanted from its biggest UK card yet. BKFC billed the May 30 show at Utilita Arena as the largest event in company history in the United Kingdom, with 10 main-card fights built around recognizable names, a title bout, and a live stream on the BKFC app beginning at 2:00 ET.

Till’s arrival was months in the making. He signed a multi-fight deal with BKFC in April after leaving Misfits Boxing on what ESPN described as extremely good terms, then entered the ring at 33 with the kind of crossover résumé promoters prize: a long MMA career, a recent boxing win over Luke Rockhold, and a public profile large enough to carry a major co-main event. BKFC has described Till as one of its biggest signings of 2026, and the promotion leaned hard into the name value that came with him.

That formula was on display against Chalmers, who came in with a 2-0 BKFC record and a prior third-round TKO over Chas Symonds. Chalmers, a 38-year-old British fighter with experience across MMA and bare-knuckle, gave the night its early drama by scoring a knockdown before Till regrouped and forced the stoppage. For BKFC, the appeal was not just the result but the packaging: a former UFC headliner, a familiar UK combat-sports figure, and a finish that traveled fast.

The rest of the card reinforced the same strategy. Connor Tierney met Rico Franco for the interim BKFC welterweight title in the main event, with Tierney listed at 9-2 and Franco at 10-3. The undercard filled out with John Phillips against Ryan Barrett, Jonno Chipchase against Brian Hyslop, George Thorpe against Leigh Cohoon, Michal Lesniak against Martin McDonough, Liam Hutchinson against Simeon Ottley, Paul O’Sullivan against Paul Hilz, Tommy Hawthorn against Will Smith, and Kris Trezise against Luke Brassfield.

Conor McGregor added a knockout bonus to every fight on the card, raising the incentive for the kind of explosive moments that bare-knuckle promotions sell best. Till’s debut showed why recognizable names keep migrating into the sport: in an attention economy, one clean knockout can matter as much as an entire season of conventional buildup.
