Marcus A. Williams (born December 12, 1977) is a former American football tight end who played in the National Football League (NFL) for one season with the Oakland Raiders. Signed to the Raiders' active roster in 2002, Williams' career came to an abrupt end due to injuries sustained from being punched by teammate Bill Romanowski during the 2003 training camp. Williams subsequently sued Romanowski and won over $300,000 in damages.
