EDEN PRAIRIE, Minn. -- Adrian Peterson missed most of Wednesday's practice because of a sore calf, but the Minnesota Vikings' All-Pro halfback is expected to return to the field on Thursday.

Peterson was kicked in the calf during Sunday's loss to Detroit, coach Leslie Frazier said. He was on the field during warm-ups on Wednesday before heading inside for treatment.

"Got kicked in the game, so just give him a chance to recover," Frazier said. "Another day of recovery. He'll be fine (Thursday)."

Meanwhile, middle linebacker E.J. Henderson was absent from practice because of continued soreness in his problematic left knee.

Henderson could get some work in practice on Thursday and should be OK to play on Sunday at Kansas City, Frazier said. He has been limited in practice since the knee swelled after the Sept. 11 season opener but hasn't missed any game action.

Peterson and Henderson both were listed as nonparticipants on the injury report. Safety Tyrell Johnson (hip) and tight end Jimmy Kleinsasser (elbow) were limited participants with newly revealed injuries, while cornerback Asher Allen (toe), cornerback Chris Cook (groin) and defensive tackle Kevin Williams (foot) were full participants.
