Packers CB Shields doubtful vs. Vikings

(AP) — The unbeaten Green Bay Packers have some health concerns going into Sunday’s game at Minnesota.

Cornerback Sam Shields didn’t practice this week and is doubtful to play because of a concussion that knocked him out of the Packers’ last game. Defensive end Ryan Pickett suffered a concussion in practice Thursday, was out Friday and is questionable for Sunday.

The offensive line, which already will be without injured left tackle Chad Clifton for a second straight game, practiced without two starters Friday.

Right guard Josh Sitton was given the day off to rest a sore knee but is probable for the game. Marshall Newhouse, who has replaced Clifton, wasn’t with the team because of a personal matter but is expected to play.
