Robins Without Suspended Duo
Bristol City go into the game with Derby County on Saturday without the services of suspended pair Liam Fontaine and Ryan McGivern.
Fontaine was sent off during the home defeat to Watford, this game will be the second of a three game ban for the player.
McGivern was shown the red card in the 1-1 draw at Middlesbrough last weekend and will also play no part.
Cole Skuse is close to a return from a broken toe, he will need to be assessed ahead of this clash, but manager Derek McInnes still has more players missing.
Lewin Nyatanga is out with an ankle problem and James Wilson is out for the season with an ankle knock of his own.
Midfielder Marvin Elliott (Achilles) and striker David Clarkson (ankle) have both been ruled out for the rest of the season.
