The Colts on Thursday signed free agent defensive end Arden Key, adding some important depth to their defensive line.
The 6-foot-5, 240-pound Key has played in 116 career games (46 starts) with the Oakland/Las Vegas Raiders (2018-20), San Francisco 49ers (2021), Jacksonville Jaguars (2022) and Tennessee Titans (2023-25). He has compiled 192 tackles, 39 tackles for loss, eight passes defensed, four forced fumbles, 96 quarterback hits and 30.5 sacks.
In 12 games (nine starts) with the Titans in 2025, Key recorded four sacks, 22 tackles, six tackles for loss and 11 quarterback hits.
The former LSU Tiger was selected in the third round (No. 87 overall) of the 2018 NFL Draft by the Oakland Raiders. At LSU, Key set a single-season school record with 12 sacks and earned first-team All-SEC honors in 2016 and 2017. Key played high school ball at Hapeville Charter Career Academy in Georgia and was ranked as the No. 6 defensive end prospect in the class of 2015.
