Pat Williams has elected to continue his legal fight with the NFL over a failed drug test, but his teammate and defensive linemate Kevin Williams has decided he's had enough. Pat Williams' attorney delivered a petition for review to the State Supreme Court on Thursday of a Feb. 8 ruling by the Minnesota Court of Appeals, which declined to block the NFL's suspensions of the Williamses for taking a banned diuretic. The players had 30 days to file a petition for review. Kevin Williams, however, decided not to pursue any more legal action in a case that began in December 2008. It's unknown whether the four-game suspensions can or will be reduced by the league through some sort of negotiation. But for now, Kevin Williams legal fight is over. Williams declined comment in a text message. If Williams serves a four-game suspension, he stands to lose about $1.4 million of his $6 million base salary for the 2011 season. "Pat and Kevin have both shown an enormous amount of dedication and frankly courage to continue to pursue this litigation," their attorney Peter Ginsberg said. "I understand Kevin's feelings that he's just had enough with the lawyers, the courts. There are important principles and protections for NFL players and Minnesota employees at stake. Pat has decided, after much deliberation, to continue. What happened to those two men is unfair and egregious and we remain optimistic that at the end of this process justice will finally win out." Pat Williams, who turns 39 in October, is a free agent and it's unclear if the Vikings will try and re-sign him. If the state Supreme Court decides to review his case, Williams likely could play another season before a final ruling is handed down. "We think there is some uniqueness to this case that merits Supreme Court consideration," said Pat Williams agent Angelo Wright. The Appeals Court declined to block the four-game suspensions of the Williamses because the banned diuretic -- Bumetanide -- found in their systems does not fall under the state's workplace drug-testing laws.
