Vikings' Harvin doubtful

Minnesota Vikings wide receiver Percy Harvin is doubtful for Sunday's matchup with NFC North rival Chicago Bears.

Harvin, who sprained his left ankle in three places during the third quarter of a Week 9 loss at Seattle, did not participate in practice this week and has missed each game since the injury.

The Vikings were hopeful to have Harvin back following the team's Week 11 bye, but the four-year pro was unable to return to the practice field this week.

Additionally, guard Charlie Johnson (toe) was listed as questionable while running back Adrian Peterson (ankle), wide receiver Michael Jenkins (foot) and cornerback Antoine Winfield (knee) were all listed as probable for Sunday.
