Harvin was limited in practice on Wednesday and Friday and missed practice Thursday to get treatment on his bruised hip, but he said he is fine.
"A lot of sprinters know when you get that pull and you just kind of ease up a little bit," Harvin said. "Coach just wanted to take yesterday as a precaution, but I feel fine."
Vikings coach Brad Childress said he wanted to take a wait-and-see approach with Harvin.
"He got out and moved around today. My concern is always the next day and the next day. He's just treating," Childress said. "He was able to step through, albeit not really full speed."
Childress said Harvin will be a game-time decision, but Harvin smiled when informed of that.
"He is the coach. I feel fine, so I guess we'll see pregame then," Harvin said.
Also limited on Friday were CBs Chris Cook and Cedric Griffin and DT Jimmy Kennedy, all with knee injuries and all listed as questionable.
Cook, who is wearing a sleeve on his knee since undergoing surgery to repair his meniscus, is more of a question mark.
"It's still up to the trainers right now and I'm still going to listen to what they say. I still haven't gotten the green light yet and I'm just waiting on that," said Cook, who missed the regular-season opener with the injury.
"After every practice I've felt better and better as every day has gone on. The first day there was a little soreness after practice."
Cook said the injury was a minor setback and that he would love to get the chance to use his height (6-foot-2) against Dolphins receiver Brandon Marshall (6-4) on Sunday. However, his injury could limit his effectiveness if he plays at all.
"Straight-line (speed) was the first thing that came back. My position is all about quick twitch. Just getting that quick twitch back is the best and hardest thing to get back," Cook said. "I'd love to be out there this week and hopefully the trainers will give me the go. If I can go, I can't wait. Great matchup."
Cook started the third preseason game, generally considered a portend of the season opener as far as starters goes, and said he believed he had done enough to earn that position before hurting his knee in that game.
"I was pretty confident in myself as far as getting the starting job. I didn't feel like I did anything to hurt it or not deserve it," Cook said. "I feel I did everything I could, made all the plays I possibly could to put myself in the position to earn that starting job."
CB Cedric Griffin is also dealing with a knee as he is working his way back from a torn anterior cruciate ligament and is also listed as questionable.
"Those guys are both going to run before the game," Childress said. "We'll probably get more of a game-time decision to watch and see how they move around."
Left tackle Bryant McKinnie has had his index finger in a wrap all week long after dislocating it against the Saints, but he's not about to let that stop him from playing Sunday against the Miami Dolphins.
"I just had to figure out what I was going to wear before the game. That was it. Just trying to let it heal," McKinnie said. "I already knew I was going to play. I've never missed a game due to injury so I don't plan on doing it now."
McKinnie will wear a glove on the hand that allows for his cast to poke through. He said he might file the cast down to give him more flexibility with the finger. He said he was just trying to ignore the pain during practice.
McKinnie was one of four players listed as probable for Sunday, joining Brett Favre (ankle/back), RB Toby Gerhart (knee) and John Sullivan (calf).
He declined to say if the team would request permission to talk to Jackson's agents.
