"Are you kidding me? Yeah, he's going to start," Jackson said.
The coach noted that Gordon, who was conditionally reinstated on Nov. 1, has enough of a grasp of the playbook to run with the first-team in his debut. Gordon began practicing on Nov. 20.
Gordon missed the entire 2015 and 2016 seasons due to suspension for repeated violation of the league's substance abuse policy. The receiver voluntarily checked himself into rehab in 2016 after participating in the Browns training camp and preseason.
The 6-foot-3 athletic freak led NFL in receiving in 2013 with 1,646 yards despite playing only 14 games. In his first two NFL seasons, Gordon earned 2,451 receiving yards, fourth-most by any player in his first two seasons since the 1970 merger (behind only Odell Beckham Jr., Randy Moss, and Jerry Rice).
"There's a question mark on it, but I know I expect to do something positive," Gordon told reporters, per ESPN.com.
Gordon's presence should immediately open the offense for quarterback DeShone Kizer, who has played his best games of the season since the Week 9 bye.
