Coach Brad Childress announced Wednesday the decision regarding Rice, who has been recovering from hip surgery in late August. The Vikings have up to three weeks to evaluate his progress before determining whether to put him on the active 53-man roster.
Also, wide receiver Percy Harvin was held out of Wednesday's practice because of a left ankle sprain he suffered in Sunday's game at New England. His status for this week's game against Arizona is uncertain.
"If I'm able to give it a go and help my team, I'll definitely be out there," Harvin said.
Quarterback Brett Favre was on the field, but he didn't have a helmet and didn't participate in drills.
Favre's injury report listing now includes three body parts: foot, ankle and chin. The elbow that bothered him earlier this season isn't currently a problem.
Favre said he passed his precautionary concussion tests following a hit he took from Patriots defensive tackle Myron Pryor on Sunday that bloodied his chin and knocked him out of the game.
He also said he's feeling "OK" despite the fact he said he woke up at 4 a.m. with throbbing pain in his left foot, which still has two broken bones in it.
"You know what? I probably should feel a lot worse," Favre said.
Childress said Rice would run with the scout team in Wednesday's practice, and during individual drills while reporters were allowed to watch Rice appeared to move around well. His return has become even more important to the Vikings following the surprise release of Randy Moss this week.
"We'll just see how he progresses here. He's done everything that he can do from a rehabilitation standpoint," Childress said. "There's going to be a conditioning aspect that's got to be met. Obviously football's a physical game: the pounding, running on the turf, the full-speed routes. We'll just see how he comes through that."
Rice had a breakout season in 2009 with 1,312 yards and eight touchdowns on 83 receptions. This is his fourth year in the NFL.
