Kevin Williams has knee surgery

Vikings defensive tackle Kevin Williams has undergone arthroscopic knee surgery, according to Jeremy Fowler of the St. Paul Pioneer Press.

The procedure was performed this week by Dr. James Andrews.

Williams reportedly does not have significant damage.  Instead, the surgery resulted from irritation that he experienced during the season.

He passed on an opportunity to replace Lions rookie Ndamukong Suh not due to injury but because of the impending birth of a child.
