A few Vikings starters with nagging injuries were held out of Sunday's preseason game as a precaution. Though a couple more players were added to the list.

At least they came away cleaner than the San Diego Chargers, who had multiple players helped off the field during the Vikings' 23-10 win at U.S. Bank Stadium.

Tight end MyCole Pruitt and safety Antone Exum Jr. are set to undergo magnetic resonance imaging scans on Monday morning, sources told the Star Tribune. Head coach Mike Zimmer confirmed Pruitt would need a MRI scan after injuring his left leg.

Pruitt, the second-year tight end, was injured on an 11-yard catch in the second quarter. He fumbled on the play, allowing Cordarrelle Patterson to recover the ball for a touchdown.

Exum Jr., a third-year safety, left in the first half after getting his leg twisted in a pileup on a kickoff return. He had an X-ray exam done, which didn't show anything, Zimmer said. Exum Jr. had a brace on his left knee after the game.

Safety Michael Griffin was forced out of the game in the second quarter when his back locked up on him, according to Zimmer. Griffin, 31, was seen exiting the locker room on crutches.

Among the Vikings starters held out were defensive end Everson Griffen, left tackle Matt Kalil and cornerback Xavier Rhodes. Second-year defensive end Danielle Hunter made the start for Griffen.

"Everson will be the starter," Zimmer said. "Just had a couple issues and he'll be fine. Like I said with Teddy [Bridgewater], I'm going to err on the side of caution with these guys."
