Vikings cornerback Captain Munnerlyn likely dodged a significant injury as he's considered "day to day" with a sprained ankle, according to head coach Mike Zimmer.

Munnerlyn exited after five snaps Sunday against the Lions with what the team announced as knee and ankle injuries. He underwent X-rays in the locker room and was able to return for one snap before exiting for good. Munnerlyn underwent an MRI on Monday morning, which didn't show any long-term damage, per Zimmer.

"He's got an ankle sprain and he's day to day," Zimmer said Monday.

'Day to day' was how Zimmer described safety Andrew Sendejo's ankle injury, just before Sendejo was held out of the Oct. 31 loss in Chicago. Sendejo returned a week later.

The Vikings defense went through a few bumps without Munnerlyn as rookie Mackensie Alexander stepped in for 18 snaps. Alexander was pulled after he was flagged for defensive holding and then allowed a one-yard touchdown grab to Lions receiver Anquan Boldin.

Zimmer responded by moving veteran cornerback Terence Newman into the slot and playing Xavier Rhodes and Trae Waynes on the outsides. Newman, 38, was once Zimmer's primary slot corner with the Dallas Cowboys back in the day and could continue to assume those duties in Munnerlyn's stead.
