Christantus Uche then made his Palace debut, replacing Pino to a great reception – and very nearly made a dramatic introduction.
Following a Mitchell cross, the ball fell kindly for the Nigerian at the back post but Roefs blocked his effort. Kamada followed up with an excellent drive that seemed destined for the net, only for the Sunderland keeper again to find a response.
That proved to be the best chance in the closing stages as Sunderland saw out five minutes of injury time.
