DONS midfielder Yoann Folly remains a doubt for Aberdeen ahead of the Clydesdale Bank Premier League trip to St Mirren.
Folly picked up an ankle injury in the 4-2 win over Hibernian last weekend and missed the midweek Co-operative Insurance Cup quarter-final defeat of Falkirk.
Zander Diamond recovered from a similar problem to play in midweek but Andy Considine (knee) and Nikola Vujadinovic (hamstring) are still struggling and Peter Pawlett (broken toe) and long-term casualty Fraser Fyvie are out.
Aberdeen manager Mark McGhee:
"Sometimes things don't go for you. At the moment, it would appear that nothing much is going for St Mirren.
"We've got to make sure that we don't change their luck.
"At the moment, it's too early to start making judgements on who might and who might not go down.
"We've got to improve. We've got to go there and start to try and put some daylight between ourselves and the other teams at the bottom."
Aberdeen: (from) Howard, Diamond, Considine, McArdle, Folly, Aluko, Hartley, Jack, Vernon, Velicka, Mackie, Maguire, Fraser, Ifil, Young, Paton, Magennis, Langfield, Vujadinovic.
