EDEN PRAIRIE, Minn. - Minnesota Vikings coach Mike Zimmer was scheduled to undergo emergency eye surgery Wednesday night, the team announced.
The Vikings play the Dallas Cowboys on Thursday night, and Zimmer's status is uncertain, according to a statement released by general manager Rick Spielman.
"Mike Zimmer is having emergency eye surgery tonight," Spielman said. "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."
Zimmer had been scheduled to have a procedure on the eye Friday morning, someone familiar with the situation told USA TODAY Sports' Tom Pelissero. The person requested anonymity because they were not authorized to speak on Zimmer's condition.
Zimmer had two eye surgeries earlier this season to repair a torn retina, both occuring in early November.
A week later, with the team in a three-game losing streak, he said this: "If I can get six needles stuck in my eye in the last two weeks, they can suck it up for me."
Zimmer would be the second NFL coach to miss a game this season due to health reasons. Denver Broncos coach Gary Kubiak was hospitalized with a severe migraine headache in October and was forced to miss the team's game against the San Diego Chargers.
Arizona Cardinals coach Bruce Arians was hospitalized after "experiencing discomfort" last week, but was released the next day and cleared to coach this past Sunday against the Atlanta Falcons.
