San Diego Chargers rookie outside linebacker Melvin Ingram sustained a thigh injury in the third quarter of Friday's 12-10 exhibition win at the Minnesota Vikings. Chargers coach Norv Turner said in the San Diego Union-Tribune that Ingram's injury is a "deep thigh bruise" and is not considered serious. Ingram, a first round draft choice, had to be helped off the field after staying down for three minutes. He did not return to the game. "That (hit) hurt," Ingram said before taking X-rays. The Chargers were already without running back Ryan Mathews, who sustained a broken clavicle in the first exhibition game. They also lost wide receiver Vincent Brown with a broken ankle in the second game. Mathews is out four to six weeks while Brown is out at least eight weeks. Both had surgery.
