HOUSTON (AP) — Houston Texans defensive end Mario Williams is out for the season after tearing a pectoral muscle in Sunday’s 25-20 loss to Oakland.
Coach Gary Kubiak says Williams will go on injured reserve and undergo surgery.
Williams appeared to be hurt while sacking Jason Campbell with about five minutes left in the first quarter. He walked to the locker room on his own, and was on the sideline in the second half, wearing a T-shirt and shorts.
Williams, the top overall pick in the 2006 draft, moved from defensive end to outside linebacker this season in new coordinator Wade Phillips’ 3-4 alignment. He was growing more comfortable with the role each week, and had five sacks and a forced fumble before the injury.
