Robinson Jr. finished with 799 yards and eight touchdowns last season, and would have led the Commanders' RB room alongside Austin Ekeler had he stayed. But now, he'll be working behind star back Christian McCaffrey as the newest member of the Niners' offense.

Brian Robinson Jr., in his 49ers practice debut, rotated in with Christian McCaffrey in an hour-long, no-pads practice.

The veteran back is entering the final year of his rookie contract and had been the subject of trade rumors this summer, and even sat out of Washington's Week 2 preseason exhibition as those talks developed. The Commanders have since found a buyer and have shipped Robinson to the Bay Area in exchange for a 2026 sixth-round pick.
