He was placed on injured reserve on January 21, 2017, a day before the NFC Championship matchup against the

Cleveland Browns On March 9, 2017, the
Cleveland Browns signed Tretter to a three-year, $16.75 million contract that includes $6.50 million guaranteed and a signing bonus of $4.50 million. In his first season in Cleveland, he started all 16 games at center. On November 7, 2019, Tretter signed a three-year, $32.5 million contract extension with the Browns, keeping him under contract through the 2022 season. Tretter was released by the Browns on March 15, 2022. On August 25, 2022, Tretter announced his retirement from the NFL.
Work at the NFLPA Having studied labor relations at
Cornell University, Tretter was elected President of the
NFL Players Association on March 10, 2020, succeeding
Eric Winston. He played a role in negotiations surrounding the
2020–2030 collective bargaining agreement, which was ultimately agreed to five days after he became president of the NFLPA. Tretter was named co-chair of the NFLPA's
COVID committee ahead of the
2020 NFL season. He represented players in negotiations that created new health and safety protocols, resulting in an average league positivity rate of 0.076% and enabling all 256 regular-season games being able to be played with no cancellations. In March 2022, Tretter was re-elected for a second term as NFLPA president. Due to his retirement as a player, he was ineligible for re-election in 2024. Starting in October, 2024, he served as NFLPA chief strategy officer, though resigned less than a year later, due in part to his and NFLPA executive directory Lloyd Howell's management of the collusion scandal surrounding Deshaun Watson's fully guaranteed contract.{{Cite web |last1=Van Natta Jr.|first1=Don |last2=Kahler |first2=Kalyn ==Personal life==
