It's probably safe to say Larry Fitzgerald isn't 100 percent healthy. But coach Bruce Arians said while the veteran wide receiver is getting an MRI today -- he didn't specify for what -- the move was precautionary and the hope is that Fitzgerald practices later this week.

"I'd be shocked if he misses a game at home," Arians said of Fitz.

Home, in this case, is not University of Phoenix Stadium but Fitzgerald's home state of Minnesota, where the Cardinals visit Sunday in a crucial game for NFC playoff hopes with both teams. The Vikings are reeling, losing four straight after opening the season 5-0. You know where the Cards are. But Fitzgerald (whose Cardinal teams are 0-4 in the regular season in their trips to Minneapolis) loves the chance to play in front of those hometown fans. Plus he ran off the field OK after yesterday's win. That's not everything, but it wasn't like he was limping around in the locker room.

Arians said Fitzgerald was "sore," but like linebacker Alex Okafor, he should practice either Wednesday or Thursday. Arians said there were no significant injuries coming out of Sunday's win. He also said safety Tyrann Mathieu (shoulder) is day-to-day and could practice this week. Mathieu also could finally discard the knee brace he's been wearing, although he will need to wear a shoulder harness when he plays.

"We should have everybody back for this one," Arians said.

The Cardinals are also eligible to bring back either running back Chris Johnson or safety Tyvon Branch to practice this week. Both could play Dec. 4 against the Redskins. Only one can be brought back from IR -- Arians said special teamer/linebacker Alani Fua is also a possibility -- and a decision on who to get back has not yet been made. Once one player from IR practices, that burns up a team's choice, even if he doesn't make it into a game.
