Viking receiver Percy Harvin missed practice Thursday because of sore ribs.  Harvin missed time in training camp because of this injury and aggravated the injury Sunday against Arizona.  Minnesota head coach Leslie Frazier expects Harvin to play Sunday night at Chicago at 7:20, pregame on WJON at 6:00.

The Vikings also practiced without defensive back Antoine Winfield (neck).  Winfield is expected to try and practice today.  Linebacker E.J. Henderson (knee) and linebacker Kenny Onatolu (hamstring) were limited in practice Thursday.
