ARLINGTON, Texas (AP) — Justin Herbert has managed well enough while playing with a broken non-throwing hand to help the Los Angeles Chargers win three consecutive games and close in on a second trip to the playoffs in two seasons under coach Jim Harbaugh. Dak Prescott and the Dallas Cowboys might be officially out of the postseason race before kickoff Sunday in their regular-season home finale. The Chargers (10-4) beat the Las Vegas Raiders the day Herbert broke a bone in his left hand, then took care of both of last season's Super Bowl teams, defending champ Philadelphia and Kansas City, with the hand heavily protected.
