The fourth-year player had 21 tackles and three sacks before being placed on injured reserve in November with a knee injury.
The 49ers were not interested in letting Blair leave in free agency, officially re-signing the 27-year-old on Monday.

With DeForest Buckner being traded to the Indianapolis Colts this offseason, there will be ample opportunity for Blair to step up and get quite a few more snaps in 2020.
