"It's a concern," coach Brad Childress said. "Your legs are your legs. We'll just see how he comes out by the time we get to Sunday."Before practice began, Peterson told reporters that he injured the hamstring late in last weekend's 18-15 loss to the Indianapolis Colts. Peterson rushed for 160 yards in the game and has 263 yards on the season, 1 yard ahead of Atlanta's Michael Turner for the league lead.
But the offense failed to score a touchdown in that game, settling for five field goals by Ryan Longwell to fall to 0-2.
"It was tough. What upset me the most is we just couldn't get into the end zone as a group," Peterson said. "The whole game I'm sitting there saying, it could come back and bite us. Peyton Manning on the other side of the ball can get hot any time. That's what happened. I was really upset."
Peterson did not specify which leg was injured, only saying that it was "pretty sore" and had him worried when it tightened up while he was pushing the pile in the fourth quarter.
"This is how we get our work done. Our legs," Peterson said. "That's the most important part of our body, so it was pretty scary."
It was so bad during the game that when Childress asked Peterson if he could return a kick to try and give the team better field position, he had to decline.
"I wasn't able to go out and give it 100 percent," he said.
If he cannot play on Sunday, backup Chester Taylor will get the bulk of the carries. Taylor was the starting running back in Minnesota in 2006, when he rushed for 1,216 yards and six touchdowns.
Taylor was demoted to backup early in Peterson's rookie year last season, but filled in brilliantly when he went down with a knee injury at Green Bay.
