ESPN's Adam Schefter is reporting that Texans linebacker Mario Wiliams suffered a torn pectoral muscle in Sunday's 25-20 loss to Oakland and is out indefinitely, with a possibility he'll miss the remainder of the season.
Williams appeared to have injured himself tackling Raiders quarterback Jason Campbell in the first quarter. Williams, the former first overall pick in the 2006 NFL draft, moved from defensive end to linebacker this season in Houston's new 3-4 scheme. He leaves with five sacks and one forced fumble.
Coach Gary Kubiak wouldn't speculate as to the severity of Williams' injury yesterday:
"I'm not a doctor, so I don't know," Kubiak said. "I hate to answer that right now in the state of mind I'm in. So let's see what happens. I'll get back with you when I find out."
Almost all of Houston's marquee players have suffered injuries this season. Running backs Ben Tate and Arian Foster have battled knee and hamstring issues respectively, and All-Pro wide receiver Andre Johnson is currently out indefinitely with a hamstring injury.
