Keon Clark didn't show up for a scheduled workout in Cleveland, ending his chances of signing with the Cavaliers.

The Cavs now have their sights on free agent center Scott Williams, who met with officials from the organization in Cleveland several days ago. Williams, 36, has been a backup forward and center for much of his career. Williams, 6-10 and 260 pounds, won three titles with the Chicago Bulls in the 1990s. Last season, Williams played in 43 games with the Suns and the Mavericks.
