Under the NFL's personal conduct policy, players who are convicted of an offense, plead guilty to a lesser offense, or plead no contest, face the possibility of a "fine, suspension without pay and/or banishment from the League."
In 2002, former Dolphins linebacker Derrick Rodgers was suspended for one game after pleading no contest to an aggravated assault charge against his wife and another man.
Last year, the NFL suspended Tampa Bay running back Michael Pittman for three games and fined him the equivalent of two game checks after he served jail time for allegedly driving his car into another car in which his wife, his 2-year old son and a baby sitter were riding. It was the second time Pittman was suspended by the league after he sat out one game in 2001, which was also the result of a domestic violence incident.
