Harvin was injured on his first catch Sunday against the New England Patriots when he appeared to have a cleat catch in the turf. He returned to the game shortly after that and ended up catching six passes for 104 yards. He didn't practice Wednesday or Thursday.
"You know, he's a tough guy. Let's face it," Childress said. "He injured that foot on his first catch of the game and still was very productive. I would just say that he's tough. Different things respond different ways. Everything goes through your foot and your ankle so he's got to have his faculties for the game the way he plays it."
Harvin is easily the Vikings' leading receiver with 31 catches (nine more than anyone else) for 393 yards (128 more than any other Viking).
After the release of Randy Moss, the Vikings could use all the help they can get at receiver, and Sidney Rice has been making his way back into practices this week after having hip surgery on Aug. 23 that landed him on the physically-unable-to-perform list at the start of the season.
This week, the Vikings activated Rice off the PUP list, giving them a three-week window to decide on his status for the rest of the season. They could activate him to the 53-man roster at any point, which seems like a likely option in the coming days or weeks, or place him on injured reserve.
"I woke up on Thursday with just a little soreness, but after Thursday's practice I felt really sore," he wrote on sidneyrice18.com. "I sat in the cold tub for like 30 minutes. That usually takes some of the soreness out. Hopefully I'll be ready for Friday and some more practice. If nothing else, I just want to get out there and run again and see how it feels."
Rice had hip surgery on Aug. 23 and told reporters Thursday that he "probably" wouldn't be playing Sunday against the Arizona Cardinals.
On Friday, he said he wasn't playing Sunday, but Childress said that was still being determined.
"He's made it through the whole practices, but in a different kind of capacity. He's taken turns with our starters. He's taken a lot of turns on the scout team," Childress said. "We've kind of mixed and matched him there. He takes the whole game plan in and goes through it. He's working through some soreness right now. You might say he could play in a limited sector. That's all being determined. I think probably next week's more viable. We're still going to see.
Last year, Rice made the Pro Bowl for the first time in his career after catching 83 passes for 1,312 yards and eight touchdowns.
In addition to Harvin, the Vikings listed CB Frank Walker as questionable with a hamstring injury.
OL Chris DeGeare (ankle), Asher Allen (back), Chris Cook (quadriceps), Brett Favre (ankle/foot/chin), Ben Leber (knee), Lito Sheppard (hand), John Sullivan (calf), Pat Williams (elbow) and Bernard Berrian (groin) are all listed as probable, meaning they are a virtual certainty to be available. Berrian was added to the injury report with a groin injury and was limited in practice Friday.
The Cardinals listed LB Clark Haggans (groin) as doubtful while RB Beanie Wells is questionable with a knee injury.
DT Alan Branch, WR Steve Breaston, LB Will Davis, WR Early Doucet and DE Kenny Iwebema are all probable.
Patriots LB Gary Guyton and DL Myron were each fined $7,500 for after they "unnecessarily struck the opposing quarterback in the head and neck area" against the Vikings last Sunday, according to the NFL.
