It was a wild UFC Fight Night main event as highly touted Czech light heavyweight Jiri Prochazka staked claim to a title shot knocking out Dominick Reyes in the second round Saturday night in Las Vegas. Prochazka's unorthodox style was on full display as he came out hands low firing punches and elbows from all angles.

But the Czech ate a big left hand in the 2nd round that left him looking for a desperation takedown. Reyes went for an arm in guillotine choke though, dropping to his back without a good angle on the hold allowing his opponent to work his head free. As they got back to their feet Prochazka relentlessly pursued Reyes, eating more punches but continuing to fire, finally launching a huge overhand right elbow that missed but spinning into a back elbow with his other arm which landed flush flattening Reyes.

Giga Chikadze also impressed in the co-main event winning his sixth straight UFC fight by slapping a roundhouse kick into Cub Swanson's liver which folded the veteran in half a minute into their featherweight bout.
