Demetrious Johnson's road back to the Octagon has already begun.
The UFC flyweight champion told MMAFighting.com that he underwent successful right shoulder surgery at a Seattle hospital on Thursday.
"It went well," he wrote via text message. "They found three tears in the labrum and cleaned them up."
The torn labrum injury forced Johnson, 26, to withdraw from his scheduled title defense on April 13 against John Moraga.
He has a postoperative visit scheduled for next Friday, and that is when he will find out how long he needs to rehab for. Twenty-four hours after the surgery, Johnson declined to say when he could return to action, although he said on Monday's episode of The MMA Hour that he was shooting for June.
"The type of surgery I had done is the labral debridement [procedure]," he wrote. "When the doctor got in there, he saw my shoulder was stable, which is the most important thing. Then I got a PRP [platelet-rich plasma] shot, which means my blood get puts in the joint which promotes natural healing in the joint where blood flow doesn't go."
Johnson (17-2-1) most recently defeated John Dodson at UFC on FOX 6 in January via unanimous decision.
