Texans RB Dameon Pierce (hamstring) is not expected to play vs. the Bills today, according to ESPN's Adam Schefter. Pierce just returned to a limited practice on Friday after missing the last three games, so it's no surprise that he's not ready yet. With RB Joe Mixon (ankle) also out, Houston will again roll with RBs Cam Akers, Dare Ogunbowale, and J.J. Taylor.
