Defensive coordinator Jason Tarver thought the defense got better as the game went on, and cited shutdowns on all five of the Jets’ third-down plays in the second half. Raiders head coach Dennis Allen wouldn’t rule out running back Maurice Jones-Drew (hand) and linebacker Nick Roach (head) for Sunday’s game after practice on Friday, even though Jones-Drew’s right hand is swollen and he hasn’t practiced all week, and Roach has been out three weeks and still not passed the last level of concussion tests.
