Breida signed his restricted free-agent tender worth about $3.3 million last week. The Niners placed a tender on Breida last month that gave them the right to match any contract or get a second-round pick as compensation.
Breida had 123 carries for 623 yards and one touchdown in 13 games last season. He added 20 catches for 120 yards and a score.
He was used sparingly down the stretch with only 17 carries for 46 yards and just 33 offensive snaps in the final three regular-season games and playoffs.
