EDEN PRAIRIE, Minn. -- Adrian Peterson missed a second consecutive day of practice on Friday, clouding the All-Pro halfback's status for the Minnesota Vikings' game on Monday against the Chicago Bears.

However, interim coach Leslie Frazier on Friday categorized Peterson's absence as "precautionary" and said he "most definitely" expects Peterson to play.

Peterson sprained his right ankle on Nov. 28 at Washington and bruised his right knee in a collision with Vikings quarterback Tarvaris Jackson in Monday's loss to the New York Giants in Detroit. Frazier said it's the knee that's bothering Peterson, who actually was hit in the thigh area.

"It's pretty sore, so we just need another day of rest," Frazier said. "We know Adrian, so he'll be fine."

Peterson hasn't spoken with reporters since Monday.

Also sitting out again were quarterback Brett Favre (chest/ankle/right shoulder), left guard Steve Hutchinson (thumb) and backup safeties Tyrell Johnson (knee) and Jamarca Sanford (concussion). None of them are expected to play against the Bears, although Frazier hasn't ruled out anyone -- including Favre, who has all but ruled out himself.

"We didn't have him do anything (Friday)," Frazier said. "We're going to try to do something (Saturday) just to see. But who knows?"

End Ray Edwards (ankle) once again was limited in practice, while cornerback Asher Allen (ankle) and quarterback Joe Webb (hamstring) were full participants.

Meanwhile, receiver Percy Harvin practiced for a second straight day and told reporters he's "feeling great" since switching to medicine for his chronic migraines.

Harvin, who has missed the Vikings' past two games, spent last week visiting a specialist at the Mayo Clinic in Scottsdale, Ariz., after meeting with Frazier and owner Zygi Wilf.

"The doctor was real confident," Harvin said. "He's treated a couple of NFL players, (former Denver Broncos star) Terrell Davis being one of the guys, so I felt real confident coming out."

Like Harvin, Davis began suffering migraines in childhood and famously left Super Bowl XXXII because of one, only to return and earn Most Valuable Player honors with three touchdowns after using a migranal nasal spray in the locker room.

Harvin has missed several stretches of practice this season, including a protracted absence in training camp -- followed days later by an on-field collapse from an allergic reaction to medication. A battery of tests subsequently pinpointed sleep apnea as a potential cause, and Harvin expressed confidence that sleeping with a breathing machine was helping.

However, this was at least Harvin's third migraine since and the first that has cost him game action.

"You get frustrated, but then I go to the doctor and I see people who can't even get out of the bed every single day," Harvin said. "I see I have it good. I realize I'm blessed. It's just something that's going to happen. Unfortunately, you can't eliminate it from happening, so hopefully, we can slow it down."

Said Frazier, "It's great having (Harvin) back out. It energizes the rest of our players. You know how dynamic he is as a player and his frame of mind is so good. He looks good. He's moving around exceptionally well. Just good for our team. He just brings a new energy to our team."

In Chicago, cornerback Charles Tillman (foot), running back Chester Taylor (knee) and linebacker Pisa Tinoisamoa (knee) were upgraded to full participation. Tillman didn't practice at all on Thursday.
