Vikings' receiver Percy Harvin is lobbying hard to return kicks for the Vikings Sunday when they play at San Diego.  Head coach Leslie Frazier is considering using Harvin in that role but could use Lorenzo Booker as the return man as well.  The Vikings are 9-point underdogs Sunday at San Diego, kickoff at 3:15, pregame on WJON at 2:00.

Viking running back Adrian Peterson ran for 296 yards against the Chargers in his rookie year in 2007.
