Texans place Mario Williams on IR

HOUSTON The Texans said Wednesday that Williams had been placed on season-ending injured reserve. He's struggled with injuries since September, and a groin injury was listed as the reason.

The team also placed wide receiver David Anderson (shoulder) and guard Mike Brisiel (calf) on injured reserve.

The Texans (5-8) play at Tennessee (5-8) on Sunday. If AFC South rival Jacksonville wins just one of its last three games, Houston will be eliminated from postseason contention for the ninth straight year.
