WWE.com has learned John Cena had surgery to remove bone chips in his right elbow today. Dr. Andrews removed several pieces of bone cartilage from Cena's elbow through a scope.

“He had begun to lose motion in his arm, and it had been locking up,” Andrews said. “I performed an orthoscopic procedure on his elbow and took out a bunch of spurs. Everything went really well.” Andrews described the procedure as “straight-forward” despite Cena’s “big, old arm.”

“Cena’s rehab will start on Monday with trying to improve his range of motion and getting the swelling down,” Andrews explained.

Cena is expected to recover in two to three weeks. As more information comes available, WWE.com will inform the WWE Universe.
