EDEN PRAIRIE, Minn. -- We take a momentary break in our wall-to-wall coverage of, well, the Williams Wall to suggest Vikings fans keep a close eye on the health of tailback Adrian Peterson.
Peterson limped to the sideline twice during last Sunday's game against Chicago. He returned to play on both occasions, finishing with 131 yards on 28 carries, but has hardly practiced this week while in serious recovery mode.
It's not unusual for a veteran running back to limit his repetitions during the week, but the Vikings are going out of their way to avoid tagging him with a specific ailment. The Vikings on Wednesday attributed his absence from practice as "rest" in their official injury report, while on Thursday the reason for his limited work was "not injury-related."
Peterson said Thursday he was "a little sore" after Sunday night's game.
"I took a lot of shots," he said. "A little beat up. Had a little rest. Feeling pretty good."
Peterson wore a brace on his right knee a few weeks ago in practice, the same knee in which he suffered a torn lateral collateral ligament last season. Asked if he took a shot on his knee Sunday night, Peterson said: ""I took a shot on my right knee, my left knee, my ankle, my foot, hip. I took so many shots, but I'm feeling pretty good."
There is every reason to believe that Peterson will start Sunday at Detroit. But his 270 carries are the most he's had in a season since his freshman year at Oklahoma in 2004, when he rushed 339 times. Whether he has a specific injury or is just sore, the Vikings are working hard to preserve their top player during the most crucial stretch of the season.
