Minnesota Vikings running back Adrian Peterson indicated he's been dealing with a right hamstring injury for the past month or so.
Peterson told Minnesota reporters that the injury began as a bruise before turning into a pulled muscle.
However, he doesn't expect to be sidelined after rushing for 28 yards on 13 carries in a loss to the New York Giants.
"I feel like it was more in my mind," Peterson said. "It's strange to say that, but I think I was kind of holding myself back, not being able to stretch out and really run. I think I was kind of hindering myself. Now that I'm able to be more relaxed and got a clearer mind, I think I'll be able to go out there and roll full-speed."
