Cleveland Browns star wide receiver Josh Gordon has allegedly failed a drug test for marijuana and could be facing a season-long suspension, according to ESPN.

Gordon told ESPN: "That's something you're going to have to talk to [agent] Drew Rosenhaus about. I really don't know anything about it."

When asked about an appeal, Gordon said, "I'm going to have to find out about that later. You need to call Drew."

Rosenhaus declined comment, adding that it's "not true."

Rosenhaus declined to comment but said the information was "not true."

Gordon was suspended without pay last season for two games and two game checks with Gordon saying he took cough syrup that contained codeine, which is a banned substance.

Brown caught 87 passes for 1,646 yards and nine touchdowns last season.

Per the report, Gordon received a letter informing him he had failed a test and faced a 16-game suspension and had been informed by an NFL doctor.
