Minnesota Vikings coach Mike Zimmer needs third eye surgery

Minnesota Vikings coach Mike Zimmer is scheduled to undergo another eye surgery in April.

Zimmer, who admitted that he still can't see out of his right eye, missed a regular-season game against the Dallas Cowboys in December after having emergency surgery to repair a torn retina.

The 60-year-old returned to the sideline the next week sporting sunglasses and a bandage.

"Hopefully that will fix it," Zimmer said, via the Dallas Morning News.

Zimmer had a torn retina in his right eye repaired following an Oct. 31 game at Chicago. He required a second surgery Nov. 8.
