John Cena to undergo shoulder surgery, could miss WrestleMania

Shoulder surgery puts John Cena's appearance at WrestleMania 32 in doubt.

John Cena says he will undergo shoulder surgery on Thursday, which could put his appearance at WrestleMania 32 in doubt. 

Cena's opponent has not been selected for WrestleMania, which will be held at AT&T Stadium in Arlington, TX on April 3. A fight against The Undertaker was rumored to be a potential match-up. 

WWE is also without former heavyweight champion Seth Rollins, who suffered a knee injury in a WWE Live performance in Dublin, Ireland in early November.
