Kevin Williams took a cheap, low block from Niners guard Joe Looney on Sunday evening and things looked really bad for him as he laid on the turf.  Then they looked a lot better as he left the field under his own power and reportedly told teammates he was fine.

On Monday, after an MRI, the news was somewhere in the middle.

Williams hyperextended and bruised his right knee during the game, or more accurately Joe Looney hyperextended his knee on a cheap shot, and his availability for the season opener is now in question.  The good news, however, is that the injury will not require surgery and Williams should not be out of action for long.

Still, following a minor knee surgery to Sharrif Floyd and Christian Ballard’s bizarre departure from the team, the team cannot afford to take many more hits to the middle of their defensive line.  This will certainly be a situation to monitor as the season opener in Detroit draws nearer.

By the way, the injury occurred on what was really a B.S. cheap shot from Niners guard Joe Looney.
