Boxers have taken a lot of heat over the years for being timid about stepping into the cage, ever since things went disastrously poorly for James Toney in a high-profile match-up with Randy Couture.

With the exception of a handful of women’s boxing stars (including Holly Holm, Amanda Serrano, Heather Hardy, and Claressa Shields), nary a boxer has stepped into the cage despite a constant stream of traffic going the other way. Male boxers especially have declined to make the jump to MMA — but former WBO Cruiserweight champ Krzysztof Głowacki is the exception to that rule, and he both showed up and showed out at KSW Colosseum 2 on Saturday.

The event took place at the PGE Narodowy, with 50,000 fans reportedly in attendance.

Despite being taken down and mounted in the opening round of his fight with Patryk Tołkaczewski, Glowacki proved he’s a dangerous striker even off his back. While mounted, Glowacki covered up, surviving a bit of ground n’ pound before unleashing a perfectly placed left hand that landed flush on the chin.

Tołkaczewski slumped forward, already out as Glowacki reversed position and landed one more strike before the ref dove in. Check out the full scene below.

That’s an impressive debut for the boxer, who put together a 32-4 record in the ring.
