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."

According to the report, Cena is still scheduled to be on RAW tonight, and additional tests will be done today to determine the full extent of his injuries.

While the article appears to be storyline, it does appear that Cena will be taking some time off.
