CLEVELAND — Days before opening training camp, the Cleveland Browns learned Josh Gordon will be missing again.

For how long remains unclear.

The troubled wide receiver, who has been suspended numerous times over the past six years by the NFL for drug violations, said on Twitter that he won’t be with the team for the start of camp as he continues to recover from addictions that have derailed his once-promising career.

Gordon has missed two full years after being indefinitely suspended by Commissioner Roger Goodell and hasn’t played a complete season since 2013, when he led the league in yards receiving and scored nine touchdowns.

While Gordon’s social media post was vague, NFL spokesman Brian McCarthy said the 27-year-old has not been suspended.

“We will address the matter at the appropriate time,” McCarthy said in an email to The Associated Press, adding “there’s no timetable” on Gordon’s return.

Gordon’s disclosure came as the Browns are preparing to begin camp.
