To push David Buehler in 2011, the Dallas Cowboys signed veteran free agent kicker Kris Brown on Thursday night.

In order to add Brown to the 53-man roster, linebacker Leon Williams (hamstring) has been placed on injured reserve, Gerry Fraley of the Dallas Morning News reports.

A fourth-round pick (110th overall) in 2006 out of the University of Miami by the Cleveland Browns, the 6-3, 250-pound Williams signed a one-year contract with the Cowboys in January.

Williams dressed for 11 games, totaling 8 tackles, six of which coming on special teams.
