As noted back in September, Lana suffered a hand injury prior to a WWE live event in Fairfax, VA. The injury happened during a training session before the show.
She was diagnosed with a Colles' fracture and doctors put in a splint. She was told that she would not be able to do anything physical for about four months.
Tuesday marked her first day back at the WWE Performance Center so she may be back within a few weeks. She can appear on television, but she cannot do anything physical until she's given clearance by WWE's doctors.
