If it was torn completely, whatever grade that might be referred to, he would have had to immobilize the foot to allow the ligaments to reattach I believe. There have been no reports of him being in a cast, walking boot or even large brace that I am aware of. In some cases, surgery is necessary to help reattach.

So as long as he is out walking around at practice and not immobilized or off his feet, my assumption is that its less than a full tear. But even that doesn't mean it couldn't be multiple weeks yet.
