Both Vikings defensive back Xavier Rhodes and wide receiever Joe Webb were full participants for the first time this week. With Rhodes playing Sunday, it helps solidify one of the Vikings' corner spots in a depleted secondary facing Bears wide receivers Brandon Marshall and Alshon Jeffery.

"We're pretty thin in the secondary and playing with a lot of guys that are out of position that you don't really want to play as much as we're having to play them because it does affect your special teams as well," Vikings head coach Leslie Frazier said. "To have Xavier back, that's a big deal."

Frazier said Vikings running back Adrian Peterson will also play on Sunday despite missing practice on Wednesday and Thursday. Fraizer said Peterson looked fine in his return to practice on Friday.

"Just trying to rest that groin a little bit and let him get treatment," Frazier said. "Not 100 percent but not to the point where it's worse than it was when we played Green Bay."

Vikings safety Harrison Smith practiced for the first time since suffering a turf toe injury against the Panthers in Week 6. While he's able to practice, Smith isn't eligible to return off injured reserve until Dec. 15 against the Eagles.

"He really looked pretty good," Frazier said. "I was telling [Vikings head athletic trainer] Eric Sugarman a little bit ago that that rule is a good rule but man I wouldn't mind if he could play this week, because he moved around well enough where you had no qualms putting him in the ballgame."
