CINCINNATI (AP) — For authorities tracking a marijuana shipment from California, the trail ended unexpectedly at the home of a Cincinnati Bengals player in suburban northern Kentucky where police say they found more drugs.

No arrests have been made. Police were still investigating the case Thursday that has entangled Bengals wide receiver Jerome Simpson, a North Carolina native in his fourth NFL season. A package containing 2½ pounds of marijuana was tracked to Simpson’s home.

The case is being investigated by police at the Cincinnati/Northern Kentucky International Airport, along with local authorities.

A Bengals spokesman said the club was aware of the reports but had no comment. Calls to Simpson’s agent went unreturned. Simpson was excused from practice on Thursday to deal with the matter. It was unclear whether he would be available for a game Sunday against San Francisco at Paul Brown Stadium.

Simpson was at his home along with girlfriend and teammate Anthony Collins on Tuesday when the woman accepted the package, said Michelle Gregory, a spokeswoman with the California Department of Justice.

Collins practiced on Thursday but didn’t make himself available to reporters for comment. Coach Marvin Lewis said Collins wasn’t a focus of the investigation, though he declined further comment.

The package originated in Eureka, Calif., part of the so-called Emerald Triangle, the state’s vaunted pot-growing region, and was discovered by a drug-sniffing dog.
