Ben Askren was taken to a Las Vegas hospital on Saturday night after suffering a brutal knockout just five seconds into the opening round in his fight against Jorge Masvidal at UFC 239.
The fight ended in dramatic fashion after Masvidal rushed across the cage and launched a flying knee that blasted Askren in the side of the head and knocked him unconscious almost instantaneously. Masvidal then followed up with two more punches before the referee was able to get in between them to stop the fight.
Askren remained motionless on the canvas for several moments after the knockout and was later helped out of the cage once he got back to his feet.
