The Miz could be out of action for up to 9 months.
It was reported on Wrestling Observer Radio that The Miz suffered a torn ACL during the Zombies Lumberjack Match loss to Damian Priest at Sunday’s WWE WrestleMania Backlash pay-per-view. He was kept off last night’s RAW, which saw John Morrison lose a non-Zombies Lumberjack Match to Priest.
There is still no word on the severity of the tear, but the hope is that it was a partial tear. If it is a full tear, Miz will need to undergo surgery and could be out of action for 7-9 months. PWInsider adds that Miz will be getting checked out by doctors this week to determine what’s next.
Apparently the injury occurred when Priest delivered a kick from the top rope, or when he delivered an elbow drop to The Miz.
