(AP) — Vikings running back Adrian Peterson practiced Thursday while wearing a brace to support his surgically-repaired right knee.

Head coach Mike Zimmer said Peterson participated in a full practice. Peterson didn't hold firm to any return date, but acknowledged his hope of being back on Dec. 24 against the rival Green Bay Packers.

The 7-6 Packers are battling the Giants, Redskins and Buccaneers for an NFC wild-card berth despite Peterson's 11-game absence.
