It is unfortunate but I don’t think there is anything your daughter can do.
I was in a similar, but slightly different position myself. I was recruited for a D1 baseball program and received a small partial scholarship. Shortly after that I injured my wrist and was unable to even swing a bat for a few months. I was able to defer the start of the scholarship for a semester but when I finally entered the school I was still in rehab but increasing activity. My coach refused to let me participate at all and even called me “damaged goods”. He tried to cut me after that season but with the scholarship deferral we forced him to honor the scholarship for a full year. I stayed with the team but the relationship with the coach never really recovered.
I had some fun times in the program but it may not have been the best move to force his hand.
