Nikola Vujadinovic will miss the game due to a hamstring injury.
The on-loan Udinese defender sustained the problem during Wednesday's win at Hamilton and is expected to be out for several games.
Darren Mackie and Fraser Fyvie remain on the sidelines with long-term knee injuries.
Dundee United will be without Danny Swanson at Pittodrie.
The midfielder came on as a substitute before being sent off for two bookable offences as United let slip a two-goal lead to draw 2-2 at Hibernian on Wednesday night.
Defender Garry Kenneth is available following a ban, meaning Jon Daly can revert back to being a striker, while Craig Conway (knee), Scott Severin (foot), Mihael Kovacevic (knee) and Darren Dods (knee) remain out.
