CFL defensive back Jonathan Hefney was charged in the United States with possessing a small amount of marijuana, just before arriving for the Winnipeg Blue Bombers 2013 training camp, the club discovered Monday.

Hefney was charged after a May 31 traffic stop in Rock Hill, South Carolina, according to a police report obtained by CBC News.

The police report alleges Hefney, 28, and a passenger, were pulled over by Rock Hill police at 1:20 a.m. traveling 47 mph in a 35 mph zone. The report says the police officer smelled marijuana as Hefney, who was driving, rolled down the window of a white Ford F-150 truck. Both occupants were searched and no marijuana was found. But a search of the truck later found 6.2 grams of marijuana in the centre console, along with a device containing some marijuana residue.

Hefney, a star defensive back with the Blue Bombers for the last four years, was issued a ticket for first offence marijuana possession.

The Blue Bombers, who started their 2013 CFL training camp on June 1, had no immediate comment on the charge, saying they are investigating the allegations.

Hefney signed with the Bombers after brief stints with the NFL’s Tampa Bay Buccaneers, Philadelphia Eagles and Detroit Lions. In three of his four years in Winnipeg, Hefney has been a Division All-Star.
