Adrian Peterson says his left knee has been a little sore and stiff this week after a successful season opener for Minnesota.
Peterson said Thursday the expected discomfort lasted about two days but is "nothing that would hold me back." He rushed for 84 yards and two touchdowns last Sunday for the Vikings, a little more than eight months after reconstructive surgery.
Peterson says he's at about 95 percent strength. He says he'll reach 100 percent soon and predicts the difference, once he regains the remaining explosiveness in his leg, will be "like night and day."
Peterson had 17 carries last week, but the Vikings (1-0) aren't ready to promise more heading into Sunday's game against the Colts (0-1).
