Answer
The UFC Welterweight title was lost by Tyron Woodley to Kamaru Usman at UFC 235 in March 2019. Usman dominated the fight, outstriking Woodley and eventually knocking him out in the fifth round to claim the title. This marked the first time Woodley had been defeated in the UFC, and cemented Usman's status as one of the top welterweights in the world.
