UFC 199 was a spectacular night of fights, with the jaw dropping KO of Hector Lombard 1:27 into the second round.
Oh, and he's 45 years old.
So a fighter, past what most people would call his career prime, just delivered a highlight worthy performance. You go, Hendo!
But instead of dreaming of what's next for him he may have just dropped a bomb on all the fans who thought the old Henderson was back.
"I'm not sure what's going to happen next," he said during his post-fight interview. "That could have been the last one of my career."
Say it ain't so, Hendo!
The crowd was obviously displeased as some 15,000 MMA fans gasped and booed at the statement.
I don't want him to retire, but I also wouldn't blame him if he made that decision.
I guess only time will tell!
