Mikel Leshoure has been suspended for two games without pay and will have to give up two more game checks for violating the NFL's substance-abuse policy. The Lions running back pleaded guilty to marijuana possession in May after police discovered him with pot in his mouth during a traffic stop in southwestern Michigan. "We support the commissioner's decision regarding Mikel and appreciate the dialogue that we have had with the league office concerning the matter," Lions president Tom Lewand said. "As we have previously stated, we expect every member of our organization to uphold a greater standard of behavior. If that standard is not upheld, those responsible will be held accountable."
