Colby Covington won bragging rights over his biggest rival and perhaps earned another title shot.

The UFC welterweight star defeated Tyron Woodley via TKO at 1 minute, 19 seconds of the fifth round last night in the main event of UFC Fight Night.

The finish was a bizarre one. Covington took Woodley down against the cage. While Woodley was going for a guillotine choke with Covington on top of him, Woodley screamed out in pain with an apparent injury.
