Star receiver Josh Gordon explored the possibility of playing in the CFL during his season-long suspension from the NFL, according to reports, but Gordon is ineligible to play in Canada while under contract to the Cleveland Browns.

Gordon's suspension for the full 2014 NFL season, the result of a failed test for marijuana, was upheld by an arbitrator on Wednesday, reportedly prompting him to consider playing in the CFL.

But multiple reports said that would not be possible due to CFL rules prohibiting teams from signing another league's suspended player. Gordon's contract with the Browns reportedly would not allow the move either.

That didn't stop the Calgary Stampeders from putting Gordon on their negotiating list, The Canadian Press reported. The move gives the Stamps exclusive negotiating rights to Gordon in the unlikely event that the Browns release him.

New rules

Fellow NFL receiver LaVon Brazill was in a similar situation to Gordon's after being suspended for a drug violation, but was allowed to sign onto the practice squad of the CFL's Toronto Argonauts on Wednesday because he was cut by the Indianapolis Colts.

Ricky Williams played for the Argos in 2006 while suspended from the Miami Dolphins for a failed drug test, but at the time the CFL did not have a rule prohibiting such a move.

Gordon, 23, topped the NFL with 1,646 yards receiving last year — 147 more than any other player, despite Gordon's missing the first two games of the season due to a suspension for violating the NFL's drug policy.

His positive test for marijuana made him a repeat offender of the policy, triggering the full-season suspension.

While suspended, Gordon can not practice with the Browns or attend any team-related events.
