According to sources close to WWE, Cesaro may have torn rotator cuff. If he seeks surgery for this treatment, he could be out of action anywhere from four to six months. This is another horrible injury that comes on the heels of Seth Rollins' knee injury and Randy Orton's shoulder injury. Elsewhere in the midcard, Rusev and Lana are both out while recovering from recent injuries.
Orton is also out with a shoulder injury and will probably miss WrestleMania.

Randy Orton's shoulder injury is apparently really serious and it's unlikely he'll be back for WrestleMania 32.
WWE might bring up more NXT wrestlers to help out.
