Cleveland Browns wide receiver Josh Gordon announced on Twitter an upcoming absence from the start of training camp to focus on his overall mental and physical health.

The NFL confirmed there are no suspensions foreseen for Gordon.

There is currently ‘no timetable for his return,’ NFL spokesman Brian McCarthy told Cleveland reporters.

“We’ll address the matter at the appropriate time,” said McCarthy.

The Browns will continue to support Gordon, who has been working hard on his substance abuse program. Gordon has been placed on the non-football illness reserve list as camp opens on Thursday.

Rumors had swirled for the past month or so on the internet that Gordon had failed another drug test, but those rumors have not been confirmed.

Gordon had been working out in Berea for most of the summer break but had recently left the team to focus on his health and treatment program. He recently posted photos of himself working out in Florida.

Cleveland Browns General Manager John Dorsey on Josh Gordon said in a statement, “We will continue to support Josh as he receives the care needed to maintain his progress. We are going to respect his privacy while he is away from the team. Josh will be placed on the non-football illness reserve list until he is ready to return.”

Gordon, 27, has been suspended for 56 of a possible 96 games for violations of the NFL’s Substance Abuse Policy since being drafted by the Browns in the second round of the 2012 supplemental draft.

He has mostly tested positive for marijuana but was also indefinitely suspended once for alcohol.

Gordon, who led the NFL with 1,646 yards in 2013, was eager to make a big splash this season after spending the offseason with the club for the first time in years. He even proclaimed at minicamp last month that the Browns have the best receiving corps in the NFL.
