The 49ers announced a one-year extension with offensive tackle Shon Coleman.
San Francisco originally acquired him in a trade with the Browns on Aug. 31, 2018.
Coleman, 28, spent last season on injured reserve.
He has appeared in 23 games with 16 starts in his four-year career since the Browns made him a third-round choice.
Coleman started all 16 games for the Browns in 2017.
