Hopefully just a badly bruised or sprained ankle rather than ligament damage.
Shame for the lad as he had bided his time, went out loan and been very professional about his time here. He's done nothing wrong on the pitch in the two spells he had getting game time. Can't see him being on too big a contract so he's all the makings of a good squad player.
