A lot can happen in a few seconds.
Jorge Masvidal posted the fastest knockout in Ultimate Fighting Championship history at UFC 239, where he froze former Bellator MMA and ONE Championship titleholder Ben Askren with a flying knee in the first round of their welterweight showcase on July 6, 2019 at T-Mobile Arena in Las Vegas. Masvidal sent the four-time NCAA All-American wrestler and onetime Olympian into another dimension five seconds into Round 1.
Askren shot for takedown right out of the gate and paid an unimaginably steep price.
