EDEN PRAIRIE, Minn. - The Minnesota Vikings have five players listed as questionable heading into Sunday's game at the Green Bay Packers.

Running back Adrian Peterson (groin), receiver Greg Jennings (Achilles), linebacker Michael Mauti (knee), defensive end Brian Robison (neck) and center John Sullivan (concussion) are officially questionable.

"A few guys that we're hoping that are going to make it to Sunday. Greg was able to get some work in yesterday and today, so that was encouraging. So we're believing that he's going to make it. Adrian got some work today so that was encouraging as well. We'll see how he feels tomorrow," coach Leslie Frazier said. "Erin Henderson is not going to make it. Still out due to a personal matter. So he won't make it."

Both Peterson and Jennings have vowed to play this week after missing practice time this week.

Robison is currently dealing with a muscle spasm in his neck, an injury he said he's never experienced before. Robison was the only one listed 'questionable' that did not practice on Friday.

"I've actually never had a muscle spasm. This is first thing for me, kind of weird. You don't think of a muscle spasm totally locking you down, and it did. We'll see what happens," Robison said. "I'm just leaving it up to the training staff, and coach Frazier."

Defensive end Everson Griffen took his place during Friday's practice and would likely get the start if Robison can't go. Should Griffen start, the Vikings may need to upgrade a practice squad end like Justin Trattou for game depth.

Sullivan (concussion) cleared protocol on Thursday night and practiced Friday. He's listed as questionable, but Frazier said he will play. He suffered the head injury during an interception return on Sunday as he was hit by teammate John Carlson when both went for the tackle on Seahawks linebacker Bobby Wagner.

Sullivan missed Wednesday's and Thursday's practices, but said the delay was due to the NFL's prolonged protocol, not because of lingering symptoms. Reserve center Joe Berger would play in relief of Sullivan should he sit at all on Sunday.

Rookie guard/center Jeff Baca stayed after practice to rep shotgun snaps on Friday.

"It was just where I was in the process, takes time. Have to go through impact test and pass that, have to be symptom free actually before you take that test, then you have to pass that test," Sullivan said. "Then you have to work out without exacerbating any symptoms or any reoccurrence [of symptoms] and then you have to see an independent neurologist."

"It's not so much I had symptoms up until Thursday, it takes time to go through all the steps and get certified [to play]."

Notes

Defensive tackle Letroy Guion (chest) will get the start at nose tackle after he sat out the past few weeks from a right shoulder/chest injury.

Running back Matt Asiata (shoulder) will return after missing Sunday's loss.

Tight end Rhett Ellison (ankle) was listed as a full participant on Friday after he was previously limited this week.
