When you’re 45 and nearly two decades into a pro-fighting career, the retirement questions are bound to pop up repeatedly. But MMA great Dan Henderson still isn’t ready to call it quits.

The former PRIDE and Strikeforce champion looks to overcome a recent 2-6 skid – admittedly, against a who’s who of top-level MMA talent – when Henderson (31-14 MMA, 8-8 UFC) rematches former UFC light-heavyweight champion Lyoto Machida (22-7 MMA, 14-7 UFC) next week in UFC on FOX 19’s co-headliner.

The middleweight bout, which is a rematch of a 2013 clash that saw Machida earn a split-decision victory, airs on FOX on April 16 from Amalie Arena in Tampa, Fla. And for Henderson, it could mark the end of one of the sport’s most accomplished and difficult pro runs.

Henderson, who first debuted in 1997 and made his inaugural UFC appearance at UFC 17 in 1998, has been asked about a possible retirement for years, so it’s hardly anything new. But the fan favorite isn’t discounting the possibility that this next bout could be it, especially since this is the final fight on his current contract.

“It’s a possibility I’ll be retiring soon,” he told MMAjunkie on Wednesday. “I don’t know – maybe after two or three more. Or maybe this is the last one. I have no idea.

“It all depends on how I feel after this fight.”

Although Henderson and UFC officials haven’t always seen eye to eye, Henderson said he speaks to company president Dana White pretty regularly about the future. However, he said he’ll rely on team members to tell him when he should consider calling it quits since they know him best.
