"Ultimate Fighter: Latin America" winner Yair Rodriguez defeated Andre Fili in spectacular fashion Saturday night at UFC 197.

The rising featherweight uncorked a vicious jump kick midway through the second round that landed flush on the chin of Fili. The Team Alpha Male fighter dropped to the canvas like a ton of bricks and the referee stepped in to stop the fight before Rodriguez could inflict any more damage.

The knockout sent Rodriguez's fellow fighters into a frenzy on Twitter, many of them impressed by the athleticism of the 23-year-old fighter. Check out some of the best reactions to Rodriguez's fourth UFC win.
