"It's not a big deal at all," said Peterson, who called the injury a minor hip pointer.
Peterson missed the first five practices of training camp before signing on Sunday a five-year, $40.5 million contract that includes $17 million guaranteed. His status is day to day, but he's unlikely to participate in weekend scrimmages against the Kansas City Chiefs.
Backfield mate Chester Taylor is also not expected to suit up against the Chiefs. He has been bothered this week by a bruised forearm.
Cornerback Ronyell Whitaker, who is competing for a backup spot, was carted off from Thursday's practice after spraining his ankle. Defensive coordinator Leslie Frazier said it wasn't serious.
