Minnesota Vikings defensive tackle Pat Williams said after the season that he was "50-50" about returning for the last year of his contract.
Almost one month later, Williams isn't so uncertain, according to his agent.
Angelo Wright told the St. Paul Pioneer Press on Wednesday that Williams has decided to play next season.
"Trust me, I know what Pat Williams is doing. Pat Williams is playing," said Wright, who added that he talked to his client "three or four times in the last week."
Williams, 37, said after last month's NFC Championship Game loss to the New Orleans Saintsthat he was mentally "drained" after a devastating end to his 13th NFL season. He even discussed retirement with Vikings quarterback Brett Favre, who has unretired twice and is considering whether or not he will return as well.
According to the Pioneer Press, Williams' 2010 salary is $4.25 million. He's also due a $250,000 roster bonus.
Williams made the Pro Bowl in 2006, 2007 and 2008, and he's the anchor of a Vikings defense that gave up the fewest rushing yards in the NFL in each of those seasons. He still might serve a four-game, NFL-mandated suspension for taking a banned diuretic if he doesn't win a lawsuit filed by him and teammate Kevin Williams against the league.
