EDEN PRAIRIE, Minn. — 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.
Receiver Percy Harvin didn't participate Wednesday but will put pads today to gauge how his bruised ribs handle contact. Coach Leslie 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.
Cincinnati: Middle linebacker Rey Maualuga wore a protective boot on his left ankle, an indication he'll be sidelined for a second straight game.
The best-case scenario has him returning for a game the following week in Tennessee.
Detroit: Quarterback Matthew Stafford was able to practice on his injured right ankle, although backup Shaun Hill took some snaps with the first team.
"It feels OK. It's sore obviously, but it's made progress since Sunday," Stafford said. "If I'm healthy enough to play, I'm going to try to be out there."
Jacksonville: Coach Jack Del Rio is limping and using a golf cart to get to and from the practice field.
Del Rio injured his left leg in Monday night's game against Baltimore. Ravens punter Sam Koch hit Del Rio while running Mike Thomas out of bounds.
Del Rio's injury came a week after Saints coach Sean Payton broke his left leg on the sideline.
New England: Tight end Rob Gronkowski says he didn't intend to hurt the team's reputation when he posed for photographs with an adult film performer.
The performer, BiBi Jones, posted two pictures of her and Gronkowski on her Twitter account on Monday. She was wearing Gronkowski's Patriots jersey in both of them. In one, he was shirtless.
San Francisco: Coach Jim Harbaugh says he is less optimistic about receiver Braylon Edwards returning from knee surgery to play Sunday against Cleveland, his former team.
