The Chargers kept three quarterbacks when they made the cut to 53 players on Saturday, but they dropped down to two on Sunday.
Jones was a Bills fourth-round choice in 2016 and the Chargers traded for him last summer. He appeared in one game with the Bills and completed 6-of-11 passes for 96 yards and an interception. He was 13-of-25 for 111 yards and a touchdown in preseason action.
The Chargers needed a roster spot for tight end Antonio Gates, who returned to the team on Sunday morning, and they’ll need two more for a pair of waiver claims. They added former Falcons linebacker Emmanuel Ellerbe and former Colts defensive tackle T.Y. McGill.
