Peterson injured his right foot Sunday when he caught a short pass from Matt Cassel, headed to the right sideline and was tackled by Arthur Brown in the second quarter of Minnesota's 29-26 loss at Baltimore.
"I haven't seen the replay,Adidas Superstar Cheap China, but my foot was extended and kind of got rolled up, kind of like a horse-collar tackle type," said Peterson, who is among the NFL leaders with 1,221 yards rushing. "I just felt it pop a couple times and the pain was excruciating. I came in and tried to tape it up again after getting the X-ray done. I just couldn't do it with the push off."
