Former WWE superstar and current contracted UFC fighter Phil “CM Punk” Brooks has suffered a shoulder injury that will slightly delay his highly anticipated octagon debut.

According to head coach Duke Roufus, Punk tweaked his shoulder during a practice session in which he was grappling. “He got caught in a scramble, so right now he’s taking a little time off,” Roufus told ESPN.com. “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.”

In December of 2014 Punk announced that he had signed a multi-fight deal with the UFC. News of the signing sent waves in both the MMA and professional wrestling communities. Punk, who has zero professional fighting experience, has met the scorn of many MMA purist who state that his signing is nothing more than a publicity stunt by the UFC.

Updates on Punk’s training and potential debut have been steady material on many MMA news outlets.  In the beginning of his training Punk and his camp have remained consistent in saying that there is no set date for his debut and that it all depends on his progress in the gym but Roufus stated to ESPN that his debut may be soon, “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.”

Fans will have to play the waiting game a little longer for Punk’s debut. In MMA injuries are common place but at 36 years old and years in the professional wrestling business, can Punk’s body be able to keep up with the high demand it takes to be a UFC fighter?
