Vikes' Favre still doubtful; Peterson ready to go vs. Eagles

Minnesota Vikings coach Leslie Frazier announced Monday that quarterback Brett Favre has yet to pass the first part of his concussion test and remains doubtful for the team's Tuesday night showdown with the Philadelphia Eagles, according to the *Star Tribune*.

Favre led the Vikings on a touchdown drive to open the game Monday night against the Chicago Bears, but he didn't make it through the second quarter after being sacked by Corey Wootton. Favre's head slammed off the frigid turf at TCF Bank Stadium, and he was knocked woozy.

The Vikings didn't list Favre, 41, as "out" Monday, as they did last week when he had a sprained right shoulder. He was upgraded to questionable the day of the game and ended up starting against the Bears.

Frazier said earlier this week that no Vikings player had participated in a game the week after suffering a concussion.

Pro Bowl running back Adrian Peterson told the Star Tribune that he will play Tuesday.

Peterson was listed as questionable with the thigh bruise that kept him out of the game against the Bears and said that the extra two days off "helps a lot."
