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."

Jerome Simpson Suspended Three Games
The NFL has suspended Vikings wide receiver Jerome Simpson for the first three games of the 2012 season.
The suspension was a result of a felony drug conviction tied to a marijuana shipment to his home last fall.
Simpson was suspended for violating the league's substance-abuse policy. He was also fined one game check, meaning he must forfeit nearly one-fourth of his $800,000 salary.
