no big deal. It's back dated to March 2nd, so he's already served 3 months and will be back in good shape by September. He's allowed to practice with the squad is he not? Not that much harm done. Just don't do it again.
Actually he can't be involved in any football related activities. I'm sure he'll be fit physically but he'll need time on the pitch.
Might be better off without him. I think having no rotation allowed company/lescott partnership to solidify. Enjoyed the name of the post.
