John Cena said on last night's WWE RAW that Zack Ryder is having surgery and will be out of action for at least. 6 months. Cena blamed Ryders injury on Rusev and The Authority after Ryder sent out a tweet about Team Cena. 

We noted before that Ryder revealed that he tore his rotator cuff and the injury caused Ryder to miss the current European tour. 

Ryders last match was last week against Rusev.
