UFC boss Dana White said he believes CM Punk should call time on his career after his most recent loss.
At UFC 225 on Saturday, the former WWE star took his record in professional MMA to 0-2 after Mike Jackson beat him via a lopsided unanimous decision.
Afterward, White was asked about whether he thinks Punk should compete again.
"It probably should be a wrap," he admitted. "The guy is 39 years old. I love the guy. He's the nicest guy in the world. We gave him two shots, and he had a lot of heart tonight in this fight.
