Koivu left the ice during Wednesday's practice with what coach Mike Yeo described as a "minor" injury. Koivu appeared to be visibly frustrated as he headed for the locker room, with the possibility that he might have tweaked the lower-body injury that has been dogging him of late. It doesn't sound like the Wild believe it will keep him out of action Thursday against the Blackhawks, but his status likely won't be officially known until the team completes its gameday skate.
