CHICAGO – John Cena's victory over Brock Lesnar came with a steep price, as WWE.com has learned the Cenation leader suffered an injured left arm in his Extreme Rules Match against the wrecking machine at Extreme Rules in Chicago. (PHOTOS)

Lesnar made it a point to punish Cena's arm in their hotly anticipated bout at Chicago's sold-out Allstate Arena, trapping his arm in a Kimura Lock halfway through their show-stopping clash. And while Cena – who also took an elbow in the opening moments of the match that split his head open – beat Lesnar by a narrow margin with an Attitude Adjustment on the steel steps, it appears he has ended up the worse for wear despite the victory.

Update: Following an MRI and a battery of tests on his left arm Monday, doctors confirmed that Cena has sustained multiple muscle strains but suffered no permanent structural damage. 

"The most obvious injury was the laceration to his head, which caused a substantial amount of bleeding," WWE locker room physician Dr. Chris Amann told WWE.com following the Extreme Rules Match on Sunday night. "He also suffered a shoulder injury."

Cena is still scheduled to appear on Monday night's Raw SuperShow, which takes place live at 9/8 CT on USA Network.
