Adrian Peterson was spotted running on the side at Tuesday's practice, marking the first time he has run in front of reporters since his Sept. 22 knee surgery.
It was the media's first look at Peterson, but the quick-healing running back had already resumed sprinting, according to coach Mike Zimmer, who said he didn't know exactly when because "I'm not in charge of the rehab."
"He's doing good. He's doing good," Zimmer said. "He's probably ahead of schedule, I guess. I don't know."
Peterson, 31, is eligible to be brought off injured reserve, although his return does not appear imminent since he still has yet to practice.
