EDEN PRAIRIE, Minn. -- The Minnesota Vikings will head into Sunday's game against the Green Bay Packers with four of their starters listed as questionable, but most of the players in question -- Greg Jennings, Jarius Wright, Matt Kalil and Sharrif Floyd -- seemed optimistic they would play Sunday.

Of the four, Floyd would seem like the biggest unknown. The defensive tackle did not practice Friday after banging knees with another player during Wednesday's practice. He said a MRI showed no damage to his knee, but the fact he did not participate on Thursday or Friday -- and had crutches next to his locker both of those days -- leaves his status in some doubt.

"It's in Coach [Mike Zimmer]'s hands," Floyd said. "I'll go as he goes."

Kalil got a day off on Friday, with what Zimmer called a "minor aggravation" to his knee. Zimmer said Kalil has been dealing with the issue for a while, and gave him a day to rest it on Friday. The left tackle said he's planning to play Sunday.

Jennings and Wright also seem likely to play; Jennings hurt his ribs on Sunday and Wright strained his hamstring, but both receivers practiced in full on Sunday.

Running back Matt Asiata, however, won't play on Sunday after sustaining a concussion last week. That could mean a larger role for Ben Tate, whom the Vikings claimed off waivers from Cleveland on Wednesday.

"He's catching on quick," Zimmer said. "He's got some explosiveness hitting the hole. Obviously he's a big-bodied guy. He's done a good job in protection so far, so we'll see how it goes."
