EDEN PRAIRIE, Minn. — Adrian Peterson has been Minnesota's most irreplaceable player since being drafted seventh overall in 2007. This season, he ran for 2,097 to be in the mix for the MVP award.
But Peterson wants to play on special teams, too.
"For the past two years, I've been trying to get in on field goal block; come in off the edge," Peterson said Wednesday. "Kickoff return, I wouldn't mind getting back there. I'm in it to win."
Peterson was asked a few minutes after special teams coordinator Mike Priefer revealed his constant request to reporters.
"Gunner, field goal block, returner," Priefer said. "I always say yes. And then I ask the head coach, and he says no."
Peterson averaged 25.8 yards on 16 kickoffs as a rookie. The Vikings used him in that role once during the regular season in 2008 and again that season in the playoffs but never since.
"I believe in having your best players on the field, especially in critical times," Peterson said. "You never know what can happen."
More Vikings: QB Christian Ponder was limited at practice but is expected to play Saturday. The right elbow of the former FSU standout hit a helmet on a follow-through Sunday.
Packers: WR Jordy Nelson and TE Jermichael Finley practiced a day after sitting. Coach Mike McCarthy said Nelson, who has a nagging knee injury, looked good running but the team doctor "has some concerns." Finley is expected to play.
Redskins: Starting LG Kory Lichtensteiger sat with a sprained left ankle sustained Sunday. And nickel CB Cedric Griffin returned from a four-game ban for a performance-enhancing substance. Their status has not been determined.
Seahawks: CB Brandon Browner returned from a four-game suspension for a performance-enhancing substance. And with fellow starting CB Richard Sherman winning his appeal of the same ban, the team is at full strength in the secondary. "We'll see how rusty (Browner) is," coach Pete Carroll said. "But we're very fortunate right now."
