EDEN PRAIRIE, Minn. -- Minnesota Vikings defensive backs Chris Cook and Jamarca Sanford practiced in full for the second straight day on Thursday, offering another indication that both players will be available to see plenty of action against the Seattle Seahawks on Sunday.
Cook (hip strain) and Sanford (groin) both missed the Vikings' last two games.
"They've had two good days of practice, so if they can make it through tomorrow, I don't know if we'll have to limit their reps," coach Leslie Frazier said. "We'll see. We have to be careful, because they're both coming off muscle pulls and playing in the secondary. We may have to take them out a series here or there, but we'll see."
In other Vikings injury news:
Wide receiver Greg Jennings was limited with an injury to his Achilles tendon, the first time he's been listed on the team's injury report with that ailment. Jennings was not on the Vikings' injury report on Wednesday, and it remains to be seen whether the injury will affect him on Sunday.
Running back Adrian Peterson did not practice, but Frazier said he was merely giving Peterson a day off, as he's done several times this season.
Defensive tackle Fred Evans, who has missed the Vikings' last two games with a knee injury, was back as a limited participant on Thursday. "He gave it a try," Frazier said. "Whether he'll be ready for Sunday, I'm not sure. This was his first day back. We'll see how he does tomorrow."
Running back Matt Asiata (shoulder), tight end Rhett Ellison (ankle), defensive tackle Letroy Guion (chest) and guard Charlie Johnson (elbow/toe) were limited. Defensive coordinator Alan Williams said on Thursday the Vikings might use Kevin Williams at nose tackle for a few snaps if Guion -- who missed the Vikings' previous game -- is still hurting on Sunday.
Lastly, quarterback Christian Ponder was limited after dislocating his left shoulder on Nov. 7 against the Washington Redskins, but Ponder continued to sound optimistic that he would play Sunday. He would wear a harness on his shoulder, but has been able to throw more than he expected in practice.
