John Cena tweeted the following cryptic tweet below this morning which has lead to speculation that he may be trying to make a return for WWE WrestleMania 32.
Cena suffered a torn rotator cuff which would reportedly keep him out until after WrestleMania 32. He underwent shoulder surgery on January 7, 2016.
The original plan was to have Cena face The Undertaker at WrestleMania.
Cena has returned ahead of schedule in the past following recovery from injury, so one could say "never say never" with regards to his latest recovery.
