The Raiders released Peterman on Tuesday, Tom Pelissero of NFL Network reports.
Peterman was brought in two weeks ago as preseason depth, and he started the Raiders' exhibition finale with Gardner Minshew and Aidan O'Connell resting. Peterman went 12 of 19 passing for 108 yards and one touchdown, but it wasn't enough to convince the Raiders to keep him on the 53-man roster. Peterman could be an emergency QB3 on the practice squad.
