"I'm playing," said Harvin, who has been dealing with sore ribs since training camp.
Good thing he's playing, too, given how short-handed the team is at receiver and kick returner. The team released former starting receiver Bernard Berrian on Tuesday, and running back Lorenzo Booker, who has been splitting kickoff returns with Harvin all season, has been held out of practices this week because of a concussion.
"It's all good. I'm not going to change the way I play," Harvin said. "The coaches don't want me to change how I play. When I'm in there, it's a hundred miles an hour. When I get banged up, I hate for that to happen, but I'm going to go (full) speed, regardless."
Harvin compared his rib injury to a hamstring injury.
"I kind of feel it pulling, so it kind of makes me nervous at times," he said. "Other than that, it's just pain tolerance."
Harvin has been wearing a protective jacket the last two weeks and will continue to do so. Last week, after taking a hit in the first half, he spent the second half watching the game on the sidelines.
"It's pretty much every week. It's just a matter of calming it down and getting as comfortable as I can to go into the game. It's just a matter of pain tolerance," he said.
Joining Harvin on the injury report as questionable were CB Antoine Winfield (neck) and Booker (concussion). Booker didn't practice Thursday or Friday, and Winfield was limited Wednesday, Thursday and Friday.
Winfield said on Thursday after going through contact drills that his level of soreness on Friday would determine if he plays Sunday, but he wasn't on the field as practice ended Friday and wasn't available for comment in the locker room after practice.
"He wasn't too bad today. Felt OK," Vikings coach Leslie Frazier said. "Not to the point where he said, ‘Coach I'm definitely ready to go.' So, we'll see how he goes tomorrow."
Anthony Herrera is out after a lateral collateral ligament injury to his left knee.
The Vikings had nine players listed as probable: RB Adrian Peterson (ankle), TE Visanthe Shiancoe (foot), DT Remi Ayodele (ankle), LB E.J. Henderson (knee), DE Brian Robison (shoulder), S Husain Abdullah (concussion), S Jamarca Sanford (concussion), C John Sullivan (concussion) and DE Jared Allen, who missed practice again Friday to see his new baby daughter, Brinley, who was born Thursday. Allen attended meetings in the morning and was "smiling from ear to ear," according to Frazier.
BUILDING A RAPPORT
Harvin said it's key for him and new starting QB Christian Ponder to be on the field together as much as possible.
"The more he can get looks at it, the more I can tell him what I'm seeing and maybe help out his throws," Harvin said. "… Ultimately, it helps (us) get into rhythm for the rest of the season."
