San Francisco signed Flannigan-Fowles (6-2, 223) as an undrafted free agent out of Arizona in 2019. The linebacker did not play during his rookie season. In 2021, he registered 29 tackles through 17 game appearances and two starts with the 49ers.
Flannigan-Fowles, 25, has recorded 38 tackles in 28 game appearances and three starts through his two NFL seasons. He was scheduled to become an exclusive-rights free agent.
The move comes a day after the 49ers signed four players—Kevin Givens and Maurice Hurst, running back JaMycal Hasty, and offensive lineman Colton McKivitz—to one-year extensions and signed quarterback Nate Sudfeld to a reserve/future contract.
