In two seasons at Youngstown State, Mason compiled 2,739 rushing yards on 478 carries and scored 31 touchdowns.

Mason eventually made the 53-man roster in 2007 but was moved to the practice squad shortly after to make room for Omar Stoutmire.

Despite leading the NFL in rushing during the 2008 preseason, Mason was released by the Redskins during final cuts on August 30.

Mason was signed to the New York Jets' active roster off the Baltimore Ravens' practice squad on October 29, 2008.

The move came a day after Jets running back Jesse Chatman was placed on season-ending injured reserve.
