The Vikings coach will have emergency eye surgery on Wednesday night, the team announced, and his status for Thursday night's game is uncertain.
"Mike Zimmer is having emergency eye surgery tonight," general manager Rick Spielman said in a statement. "His status for coaching tomorrow's game is uncertain. I have met with the coaches and players and we have a contingency plan in place if Mike is unable to coach against Dallas."
