Giants quarterback Eli Manning isn't guaranteeing that he'll play against the Raiders on Sunday. Manning, who has started 82 straight games, was held out of practice on Wednesday. "If I feel like I can go out and play at a high level and help the team and do everything I can do, and they don't have to limit the game plan or say you can't do this or that, I'll go out there and play," Manning said. "I'm not going to do anything that will put myself in harm for making this worse down the road." Manning admitted his heel bothered him occasionally the last few weeks, but nothing like it did in the fourth quarter against the Chiefs on Sunday.
