Barrett had signed a one-year deal with the Miami Dolphins in March after being released by the Buccaneers in a cost-cutting move.

The 31-year old Barrett spent five seasons in Tampa, including the 2020 campaign that resulted in a Super Bowl title with quarterback Tom Brady at the helm.

Barrett and his family suffered a tragedy in April 2023 when his 2-year-old daughter, Arrayah, drowned in the family's pool. He returned for the start of the 2023 season and registered 4.5 sacks and 52 combined tackles, including 33 solo tackles.

An undrafted free agent out of Colorado State in 2015, Barrett has 59 career sacks in nine seasons with the Buccaneers and Broncos, where he captured his first Super Bowl title in 2015.

He led the NFL with a franchise-record 19.5 sacks in 2019, his first season with Tampa Bay. Barrett reached double-digit sack totals in just one other season: 2021, with 10.
