Receiver Percy Harvin wasn't on the field during the brief beginning portion of Vikings practice that was open to the media. Harvin earlier said he would try to practice, but the Vikings obviously thought otherwise.

Vikings coaches said he went through some work with head athletic trainer Eric Sugarman, and the team's injury report said he did not participate in practice.

Harvin sprained his left ankle against the Seahawks on Nov. 4, missed the following week's game against the Lions and had last week's bye to further his recovery. He's expected to play against the Bears on Sunday.

Guard Charlie Johnson (toe) also did not participate. Defensive tackle LeTroy Guion (foot) and receiver Michael Jenkins (foot) were limited, as was cornerback Antoine Winfield (knee).

The Bears did not practice, but issued an injury report. Quarterbacks Jay Cutler (concussion) and Jason Campbell (ribs) were listed as players who would have had limited participation.
