Despite an appeal -- in which Garrett accused Rudolph of inciting him with a racial slur, which Rudolph denied -- the suspension was upheld and Garrett missed the final six games of the season.
"We welcome Myles back to our organization with open arms," Browns general manager Andrew Berry said in a statement. "We know he is grateful to be reinstated, eager to put the past behind him and continue to evolve and grow as a leader. We look forward to having his strong positive presence back as a teammate, player and person in our community."
Garrett, the No. 1 overall draft pick in 2017, had 10 sacks before the suspension.
