At 38 years old, Brock Lesnar proved he's still a monster in the octagon on Saturday with a unanimous decision win over Mark Hunt in UFC 200.
The former UFC heavyweight champion had not fought since losing to Alistair Overeem at UFC 141 in December 2011, leaving due to diverticulitis.
Despite making a winning return following more than four years away from MMA, the WWE cross-over star is unsure if he will look to build upon his 6-3 record.
"Well let's get one thing clear, Brock Lesnar does what Brock Lesnar wants to do," Lesnar said.
"I believe that my future's already laid out for the next month. I'm doing [WWE] SummerSlam against Randy Orton. Once the dust settles there I don't know what I'm going to do.
"I had one hell of a time tonight [Saturday] and I enjoyed myself so we'll see what happens. It's really way too soon.
"I've been gone for five years, I stepped into the octagon tonight with a guy ranked number eight in the world.
"You can write what you want to write, but I think I'm the toughest son of a b**** and I'm top 10 and it puts me right in the game. If I want to make that decision to keep fighting, I will."
