According to NFL Network’s Ian Rapoport, the Indianapolis Colts are not expected to tender restricted free agent defensive tackle Taylor Stallworth (via his representation), making him an unrestricted free agent:
The former 2018 undrafted free agent of the New Orleans Saints recorded 16 tackles (11 solo), 3.0 sacks, and a pass defensed during 16 games (1 start) for the Colts in 2021.
Per PFF (subscription), Stallworth was their 53rd best graded interior defender this past season with a +60.
