Chargers' cornerback Quentin Jammer will miss Sunday night's home game against the Indianapolis Colts because of a hamstring injury, meaning Antonio Cromartie will make his first pro start. Jammer injured his hamstring against Houston on Oct. 28 and aggravated it against the Vikings. The team listed him as doubtful on Friday's injury report, but the cornerback said he won't be in uniform. "I'm going to have to be smart about the injury," Jammer said. "I feel I could probably go, but I felt like I could go last week and it ended up catching again and set me down for another week. I don't want that to keep happening."
