Big Pat stays mum

One day after his agent officially ended talks on a contract extension, defensive tackle Pat Williams had nothing to say about this possibly being his final season with the Vikings.

Unable to reach agreement on an extension, agent Angelo Wright said Friday that Williams, who brushed off interview requests following the morning practice, will play out the final season of his contract and enter the free-agent market.

First-year defensive coordinator Leslie Frazier praised Williams' leadership qualities and said he doesn't expect Friday's developments to affect the 11-year veteran's play this season.

"He's a leader for our defense, without question," Frazier said. "He's a guy who is not only a leader by his example, the way he plays, but verbally as well. I love being around him. The short time I've been around him, I've really enjoyed. He's a very, very valuable member of our football team and a joy to work with."

Injury note: Linebacker Ben Leber missed the morning practice because of a strained calf, but Frazier said he's expected back in a few days.
