Vikings' wide receiver Percy Harvin is listed as "doubtful" for Sunday's game against NFC rival Chicago.
Coach Leslie Frazier says Harvin made a brief appearance at practice Friday but wasn't able to put much weight on his sprained ankle. Rookie Jarius Wright is active for Sunday and will most likely take over for Harvin should he miss the game.
Left guard Charlie Johnson and nose tackle Letroy Guion were listed as questionable with toe injuries.
Bears' quarterback Jay Cutler was limited again in practice Friday and will meet with an independent neurologist on Saturday to find out if he'll be cleared to play Sunday.
