Carolina plans to sign running back Stephen Davis this week to a one-day contract allowing the Spartanburg, S.C., native to retire a Panther, according to the Rock Hill Herald. Davis, who finished up his career in St. Louis, led the Panthers to the Super Bowl in 2003 when he ran for a career-high and single-season franchise-record 1,444 yards. Davis was a member of Carolina's 10-year anniversary team.
