The Kansas City Chiefs have kicked the tires on some nose tackles in a recent workout.

The club put veteran William Joseph, Tim Anderson and Marlon Favorite through tryouts, a league source said.

First-year head coach Todd Haley has made it clear he is not done working over the roster, and the Chiefs have been as active as just about any team in exploring player additions.

Kansas City doesn’t show any tackles on its injury report for Sunday’s game against the Dallas Cowboys. Joseph is the most experienced of the bunch. He spent time in Oakland before the Raiders traded for Richard Seymour.
