The Cleveland Browns will be without wide receiver Josh Gordon for the start of training camp Thursday as part of his “overall health and treatment plan.” Gordon made the announcement himself via Twitter.

“To my Cleveland Browns and NFL family, I am reaching out to you all personally and letting you know that I am not only doing great physically but mentally as well,” Gordon tweeted. “You will notice that I will not be in Cleveland for the start of training camp. Rest assured this too is a part of my overall health and treatment plan.

“I appreciate the awesome support I have received from teammates, friends, fans, and the Brown’s organization. Just like you, I am excited to start the season and I have every intention of being ready and available to join my teammates soon to help bring winning football to our fans.”

Gordon has missed most of the last three seasons because of suspensions related to violations of the NFL's substance abuse policy. After missing all of the 2015 and 2016 seasons, he played the final five games of last season, tallying 18 catches for 335 yards and one touchdown.

Shortly after Gordon’s announcement, the Browns released GM John Dorsey’s statement which says they’re placing Gordon on the non-football illness reserve list “until he is ready to return.”

Big things are expected from Gordon this season. With him and Jarvis Landry leading the way, the Browns have the potential to have one of, if not the best wide receiving corps in the league this season.

While this health and treatment plan will keep Gordon out for the start of camp, it successfully keeps him on the field once the regular season actually begins.
