Giants wide receiver Mario Manningham missed practice on Friday with a left shoulder injury. He suffered the injury on the final play of practice on Thursday. "They thought it was better if he just not work today," coach Tom Coughlin said of holding him out on Friday. "So I'm going to list him as questionable, but hopefully he will make it." Manningham has started six of seven games this season, catching 28 passes for 439 yards and four touchdowns.
