John Cena Injured At Extreme Rules

WWE wrote on their website after Extreme Rules that John Cena suffered an injured left arm during his match with Brock Lesnar at Extreme Rules in Chicago.

"The most obvious injury was the laceration to his head, which caused a substantial amount of bleeding," said WWE locker room physician Dr. Chris Amann. "He also has suffered a shoulder injury. Initial testing in the training room leads me to believe there may be torn muscles, possibly a torn rotator cuff or a biceps muscle."

Following an MRI and a battery of tests on his left arm Monday, doctors confirmed to WWE.com that John Cena sustained multiple muscle strains during his Extreme Rules Match against Brock Lesnar.
