Offseason workouts for the Minnesota Vikings are set to begin on Monday. But the team will be without one key member, coach Mike Zimmer.

The coach will have the first of two scheduled surgeries on his right eye, this time around, that is. The one he’ll have Monday is actually his fifth in total.

“The two operations on Zimmer’s right eye will be the fifth and sixth he’s had since Nov. 1, the day after he scratched his eye during a loss to the Chicago Bears and exacerbated the vision problems he’d been having prior to the game,” ESPN’s Ben Goessling wrote. “Zimmer missed the Vikings’ game against the Dallas Cowboys on Dec. 1, and had another surgery on Dec. 2, but returned to practice the following week and coached the rest of the season.”

Goessling noted that in Monday’s surgery, “doctors will remove the oil bubble that’s been on Zimmer’s eye since last December and replace it with an oxygen bubble to help allow his detached retina to heal.”

The following surgery, according to Zimmer, will be for cataracts.

For Zimmer’s sake, these will hopefully be the final procedures. Going through six operations in less than a year on the same body part has to have taken a toll on him. Even for a well prepared coach, it also has to have had some effect on his coaching, as well.
