Kansas City promotes guard

Posted by ESPN.com's Bill Williamson

Another week, another Kansas City roster move.

The Chiefs signed guard Tavares Washington to a three-year contract. Washington had been on the Chiefs practice squad for the past 10 weeks.

Washington was on San Francisco's practice squad for the entire 2006 season and he spent a part of last season on the 49ers practice squad. He was with Washington in training camp this season.
