Giants' quarterback Eli Manning insists that he'll play on Sunday against the 49ers despite an apparent chest injury. Manning claims that the injury is "nothing major". It appeared to occur in the second quarter, and the quarterback never missed a play on Monday night against the Browns. "He got hit and then he was driven into the ground, and his chest was bothering him after the game," Coach Tom Coughlin said Tuesday. "He was in some pain there, but I don't have any information other than that. He was in the training room. We'll see."
