Loree Moore has apparantly confirmed that the injury was not Beard's fault.

According to Melanie Jackson, Moore spoke to Alana Monday night and told her that the injury happened on the jump-stop before Alana even got there.

As I said earlier, this seems to make sense, given that it was the left ACL that was hurt. Plus, I'm not doctor, but I think many/most of the ACL tears I've seen have been from jump stops.

Voepel also weighs in at the same link above and says people should stop blaming Beard.
