#1. Dean Ambrose
Dean Ambrose is one of the most high profile injuries in WWE right now, the former World Champion suffered a torn tricep back in December and the prognosis was that he would be on the sidelines for up to nine months.
There have been many updates regarding Ambrose's future over the past few months that have stated that the former Shield member is now in Birmingham, Alabama where he has been rehabbing his injury ahead of a return to the ring.
If the original timeline for his return is taken into account then Ambrose should be back on WWE TV before the end of September, but many other rumors suggest that he could make his return as part of SummerSlam season and he currently looks as though he could be ahead of schedule.
