First-half goals by Tom Lawrence and Wayne Rooney ultimately proved to be the Royals' undoing at Pride Park - Andy Rinomhota's header gave hope but the Royals couldn't complete what would have been a deserved fight-back.
Lawrence and defender Matt Miazga were each shown a red card after the final whistle too, following an altercation.
A close-run affair but nothing to show for it for the Royals.
