The NFL has suspended fullback Luke Lawton for four games for violating the NFL policy on performance enhancing substances.
Lawton will miss the Cleveland and Baltimore games this season, and the first two games of the 2010 season without pay. He started three games this season and played in all 13.
That leaves the Raiders with only converted halfback Gary Russell as the lone fullback on the roster. The Raiders have one fullback, Marcel Reece, on the practice squad who could be activated to face the Browns.
