EDEN PRAIRIE, Minn. (AP) — Minnesota Vikings coach Mike Zimmer is recovering from surgery to repair a torn retina in one of his eyes.

Wearing sunglasses to limit the outside light at his news conference Wednesday next to the team's practice fields, Zimmer said he'd had vision trouble for a couple of days before scratching his eye during the game Monday in Chicago. He was sent for further examination and a procedure done Tuesday by doctors who warned him he risked blindness if he didn't address the problem.

Zimmer said he's been watching film with his good eye, using reading glasses so he can write down notes.

The Vikings play Sunday at home against Detroit.
