If free safety Ed Reed's appeal of a one-game suspension is unsuccessful, Ihedigbo would step in as his replacement against the San Diego Chargers. Against the Steelers, Reed's backup delivered a punishing hit on his sack of Leftwich. "A window opened up, and I went for the kill," Ihedigbo said. "That's what I'm here for." Should Reed's punishment be upheld, Harbaugh has confidence in Ihedigbo. "James played really well, he was a physical force out there," he said. "We said something to him after the game and he said, 'That's what you brought me here for.' He's got a lot of pride, and he fits right in." ... Due to the Thanksgiving holiday and traveling to the West Coast on Friday, Harbaugh is tweaking the practice schedule to account for the time change. Practices will start later on Wednesday and Friday. "There will be a little bit of a time crunch there because we're leaving early, because we'll have a shortened on Thursday with Thanksgiving to give the guys a chance to be with their families," he said. "So, we're going to have to pack a little more work into a little less time and then we're going to have to adjust for the time change."
