The Bengals lost both centers to knee injuries during the first half, forcing guard Eric Steinbach to take off his gloves and play the position. Rich Braham, the Bengals' 12th-year veteran, hurt a knee during the second quarter against the Houston Texans. The severity of the injury wasn't immediately known, but the Bengals said he wasn't expected to return. Backup center Larry Moore hurt his right knee while blocking on a run play later in the second quarter and was taken off the field on a cart.
