If it were my athlete, I would take that to mean absolutely no stunting for that entire time. Risks of things colliding with the jaw would be too great, no matter the skill being performed. I'd condition the heck out of that athlete and work on flexibility. (Is she a flyer? She could spend the time working on body positions on the floor/brick.) If she's a base/back, she could work with weights. She could work specific conditioning drills to help her jumps and tumbling without actually doing the skills.
As far as tumbling, I may be on the ultra-conservative side here, but... I'd only have her do skills that she is comfortable with - no moving on to additional skills at this time. Work on getting an absolutely perfect front/back walkover, absolutely perfect BHS. I probably wouldn't have her tuck because I've seen lots of athletes accidentally knee themselves in the face randomly, even if they were completely able to perform a tuck usually. I'd have her do everything else with the team, once she is feeling better after the surgery. It is important for her to feel like she's still a part of the team, even if she can't do everything at this moment. The support of her teammates will help immensely.
