Patriots' linebacker Adalius Thomas broke his arm against the Bills on Sunday, according to sources. Thomas left the field in the second quarter. He did not return and later was seen leaving the locker room with his arm in a sling. "I don't want to speculate now. Obviously, he didn't come back into the game. That's never a good thing," Richard Seymour said. "It'll be a big loss for us, if he's not out there. He brings a lot to the team."
