Texans defensive end Mario Williams has been playing with a sports hernia. Williams has been listed on Houston's injury report with a groin injury. "He's been battling through that all year long," coach Gary Kubiak said. "Obviously it's been bothering him, but he's been fighting through it. "I know it's bothering him, just watching him play (at Philadelphia), watching him try to fight through it. He had some injections on Wednesday in Philadelphia. Sometimes it takes a few days for those injections to kick in. "He's been doing all he can. We'll continue to treat him the same way we've been doing it, trying to bring him along to each game day. He's trying to give us everything he's got."
