is reporting that Mark Henry is believed to have suffered a hyperextended knee at the Smackdown taping on Tuesday in Tucson. The injury reportedly occurred when Henry was throwing a punch and his knee moved forward before he planted his foot. This forced the crew to call an audible for the finish of Smackdown tonight involving Daniel Bryan and Big Show. Despite this injury and working through a recent groin injury, Henry is expected to wrestle at Sunday’s Royal Rumble PPV.
