Pro wrestling star CM Punk’s switch to the world of mixed martial arts endured a setback recently.

Punk, whose real name is Phil Brooks, sustained a shoulder injury in training according to an ESPN report, and will be shelved for several weeks.

The news came from Punk’s trainer Duke Roufus, who works with MMA luminaries like former UFC lightweight champion Anthony Pettis and Bellator welterweight champion Ben Askren.

“He got caught in a scramble, so right now he’s taking a little time off,” Roufus said. “He was doing great before that. His progress has been good. He’s got a great attitude and he’s a hard worker. He got a place in Milwaukee where he lives all week when he’s here training, so he’s in it to win it.”

“Our biggest thing is we want him to 101 percent before [we resuming training],” he said. “We don’t have a hard date for his fight to force the issue, so making sure he’s completely healthy is possible.”

Punk is scheduled to see a doctor October 14 and may be cleared to resume training.

“The UFC will probably book him a fight three to four months in advance — a guy of his magnitude,” Roufus said. “We’re probably looking at a fight in the next six to 10 months. The injury throws us back one month. We had a ballpark. We were looking at mid- to late-spring. Now, we’ll just have to see how he comes back from the injury.”
