Brock Lesnar represents Paul Heyman in his brutal attack of CM Punk.

CM Punk demanded an explanation from Paul Heyman on Raw, but what he got instead was a slew of injuries at the hands of Brock Lesnar.

Moments after The Straight Edge Superstar vowed retribution against Heyman for betraying him at Money in the Bank, the mad scientist summoned Lesnar to tear Punk to pieces. The Anomaly rammed Punk into the steel ring post, tossed him into the ringside barrier and capped off his assault with an F-5 onto the announce table, and according to WWE medical officials, the damage to Punk was severe.

In what sounds more like an injury report from a car crash than a fistfight, medical officials have told WWE.com that Punk suffered whiplash and strained ligaments in his left knee and right ankle. Punk’s ribs are also bruised, potentially broken, as a result of the attack.
