Tamina Snuka recently underwent surgery for a torn rotator cuff. Snuka last appeared at last month's Women's Royal Rumble match and wrestled with the injury. She had the surgery two days later.
It appears as if Snuka's participation in the Rumble match was questionable. As we noted before the Rumble, she was removed from promotional material for the match at one point, before being re-added. She entered the Rumble match at #7 and lasted less than two minutes before being eliminated by Lita.
Jeff Hardy has been out of action since undergoing surgery for the same injury last October. The timetable for a return from the surgery is usually 6-8 months.
