The 49ers announced the signing of linebacker Demetrius Flannigan-Fowles to a one-year extension. That keeps Flannigan-Fowles in San Francisco through the 2022 season.
He was scheduled to become an exclusive rights free agent.
The 49ers signed Flannigan-Fowles as an undrafted free agent out of Arizona in 2019. He did not see any action during his rookie season.
Flannigan-Fowles, 25, has totaled 38 tackles in 28 games. In 2021, he made 29 tackles in 17 games, including two starts.
The 49ers signed four players to one-year extensions Thursday and signed quarterback Nate Sudfeld to a reserve/future contract.
