From my Associated Press feed at work:
"Just from what I've seen and heard, he'll be out there." -- Domenik Hixon
"Knowing him and knowing how confident he is, I'm pretty sure he'll be ready to play come Sunday." -- Chris Snee
And from Matt Moseley: "Manning has said he intends to play. Coughlin said he's willing to take the decision whether or not to start Manning until game time Sunday. He said Manning could play even if he did not practice all week."
