EDEN PRAIRIE, Minn. (AP) — Minnesota Vikings cornerback Antoine Winfield will be a full participant in practice Thursday, hoping to test his injured neck and see if he can play in Sunday’s game at Carolina.

Winfield wouldn’t specify details about his injury after participating on a limited basis Wednesday, but said it’s “more than a strain” and that the decision on whether to play is all his. Winfield has missed the last three games because of the problem.

Guard Anthony Herrera has damaged his surgically repaired left knee and is unlikely to play against the Panthers. Coach Leslie Frazier said Herrera will probably be listed as doubtful on the injury report after damaging the lateral collateral ligament in the knee. Herrera was not on the field for Wednesday’s practice.

Center John Sullivan has been cleared to return from his concussion after missing the last game against Green Bay. The same goes for safety Jamarca Sanford.

Receiver Percy Harvin didn’t participate Wednesday but will put pads on Thursday to gauge how his bruised ribs handle contact. Frazier said Harvin is feeling better and expects him to play this weekend.

Running back Adrian Peterson and tight end Visanthe Shiancoe also sat out of Wednesday’s practice. Peterson hurt his ankle in Sunday’s game but said the injury wasn’t serious, and Shiancoe was listed with a foot problem.
