The Browns officially moved Gordon to the active list off the non-football injury list, which allows the 2013 Pro Bowler to participate in walk-throughs beginning Saturday.
"Josh Gordon is going to go into the second phase of the process that we have him on. He will definitely be involved in walk-throughs," coach Hue Jackson said Friday. "He is definitely getting into the next process for us. He will definitely be involved in the walk-throughs and doing some other things."
NFL spokesman Brian McCarthy said in a statement that Gordon has been cleared for all activities, including games.
Gordon had left the team prior to the opening of training camp to get help with his mental health and returned to the team last week but was not able to participate in walk-throughs or practice after being place on the non-football injury list.
Gordon participated in the team walk-through Saturday, but he did not go through a full practice because of tightness in his hamstring that occurred during conditioning since his return last week.
"He just tweaked it, so I am not going to put him out there until he is totally ready to go," Jackson said. "It's a little minor setback but we will get him out there soon."
Jackson said that it was doubtful that Gordon would see action in the preseason finale against the Detroit Lions, but the coach still hoped to have him ready for the season opener against the Pittsburgh Steelers on Sept. 9.
"If there is a chance against Detroit at the end, it would be great," Jackson said last week. "If not, my real goal is can we get him up and running by the time that we play Pittsburgh? I think that is really important."
There is reason to be excited if Gordon can ever regain the form that saw him catch 87 passes for a franchise-record 1,646 yards in 2013, despite missing two games. But being on the field has been the problem throughout Gordon's career, as he has played in just 10 games for the Browns in the past four seasons combined.
When Gordon gets back on the field, he will team up with Jarvis Landry, whom the Browns acquired this past offseason. Landry, who is coming off a year in which he led the NFL in receptions in 2017 with 112 and has averaged 105 catches per season over the past three years, is looking forward to playing with Gordon.
"I am excited to play with him, excited to work with him, and compete with him," Landry said last week. "That's what's going to help us get to the level we need to be at to win games."
