Payton, 24, was taken in the fifth round of the 2016 NFL draft. He was in the second year of his four-year, $2.584 million contract and set to make a base salary of $540,000 for the 2017 season when the Browns waived him coming out of the preseason.
Payton served a four-game suspension for violating the NFL’s performance-enhancing drugs policy last year.
In 2016, Payton has appeared in four games for the Browns but has caught just a single pass for three yards and no touchdowns.
