a strong start to the 2019 season, Ablett was offered a one-match suspension, which would have been the first of his career, after striking Essendon midfielder Dylan Shiel with a forearm to the head in the Cats' round 7 win; the club chose to appeal the suspension at the AFL Tribunal and was ultimately successful, maintaining Ablett's clean record. An almost identical incident occurred the following week involving North Melbourne utility Sam Wright, but Ablett was not penalised. A third incident followed a fortnight later, this time a punch to the jaw of Gold Coast midfielder Anthony Miles; he was again offered a one-match suspension, which the club chose to accept, meaning that Ablett was suspended for the first time in his career after 331 games to that point.

After finding out that he would not be allowed to return to play until the final home-and-away round due to Queensland travel restrictions, Ablett joined two players in the AFL's Gold Coast quarantine hub in September, before returning in Geelong's win against Sydney in round 18. He was among the best afield in Geelong's preliminary final win against the Brisbane Lions at the Gabba, kicking two third-quarter goals among 14 disposals. Ablett played his final game in Geelong's 31-point loss to in the 2020 AFL Grand Final the following week; he injured his left shoulder in the opening minutes of the game but continued to play, with scans later revealing that he had played out the rest of the match with a broken shoulder.
