I sort of wish this thread would go away at this point. We know a few things, and we will not know anything more until we get more specific information from either the team directly or from something specific the horde writes.
1. DJB has a nagging achilles injury and has had issues with her previously injured wrist.
2. DJB has some unspecified but serious academic issues that the team is dealing with by removing her from the public aspects of team activities.
3. Butler has been medically cleared to play for a couple of weeks. Medically cleared is NOT the same as healthy. It is a status indicating doctors believe the healing has reached a point where normal activity, possibly with a medically indicated protective device, will not lead to further injury or retard the healing process. (It can also indicate a status that a player who still has an injury will not risk further injury by continuing to play.)
4. Geno and the coaches have determined that Butler is not in fact ready to play. This does not represent a 'set-back' necessarily, just that her performance in practice has not been good enough to warrant her playing yet. This is pretty standard stuff for athletes returning from injury - confidence, trust in the injured area, compensation for a still weakened area, stamina, pain threshold, and numerous other reasons might be the cause. With a ten day exam break on the horizon and the team playing well, there was no pressing need to rush the return to the court.
Everything else is speculation, and a lot of that speculation is about personal issues of players that are not our purview on this board.
