Bears running back Thomas Jones (who has been out with a hamstring injury) will start in tonight’s preseason game against Arizona.  Jones is competing with the also injured Cedric Benson for the starting spot.  Benson’s strained relationship with his teammates is no secret.  He left the last preseason game early and will not play in tonight’s game.  Perhaps it was no accident that his shoulder got tweaked after his run in with Urlacher in training camp.
