(Minneapolis, MN) -- Vikings defensive tackle Kevin Williams may face cross-examination by N-F-L attorneys today in Minneapolis in his lawsuit against the league. Williams and teammate Pat Williams claim the N-F-L violated state law when they were tested for drug use during 2008 training camp in Mankato. Both tested positive for a banned diuretic, but their four-game suspensions have been held up through legal maneuvers. Kevin Williams testified yesterday, saying he has never taken steroids or substances that mask the use of performance-enhancing drugs. He told the court the substance that was found in his system contained natural ingredients that were listed on the label. It's likely that Pat Williams will take the stand today in the Hennepin County Government Center.
