Farrell logged 27 snaps on offense and wasn't targeted in Sunday's 42-38 win over the Bears.
George Kittle (ankle) was sidelined for Week 17, but it was Jake Tonges (7-60-1 receiving line) who stepped up to provide the most fantasy value among 49ers tight ends in the primetime win. Farrell remained in his usual blocking role, earning similar playing time to games in which Kittle had played.
