O'Connell (coach's decision) is inactive but will serve as the Raiders' emergency third quarterback against the Dolphins on Sunday.
Kirk Cousins beat out first-overall pick Fernando Mendoza for the starting quarterback job Week 1, so O'Connell will suit up as the emergency QB3. As such, O'Connell is prohibited from playing Sunday unless both Cousins and Mendoza were to leave the game due to injury, illness or ejection.
