Houston Texans linebacker Mario Williams suffered a torn pectoral muscle against the Oakland Raiders on Sunday. 

The former #1 overall pick in the 2006 NFL Draft will be sidelined indefinitely with a torn pectoral muscle.  Williams might be lost for the entire season.  It's believed that Mario suffered the injury while sacking Oakland Raiders quarterback Jason Campbell on Sunday.  The Texans lost the game to Oakland 25-20.

Williams has five sacks and a forced fumble this season.  He had a breakout season in 2007 when he recorded 14 sacks in his second NFL season.  He followed the '07 season with an impressive 12 sacks in 2008.
