Dons boss Derek McInnes today refused to rule out adding another new signing ahead of the Euro tie against Latvia’s Ventspils.
Aberdeen face Ventspils in the Europa League second qualifying round fist leg at Pittodrie on Thursday.
Despite a 1-0 loss to Fola Esch in Luxembourg the Reds progressed 3-2 on aggregate.
The Uefa registration deadline for new signings for the second qualifying round was yesterday.
However, there is dispensation to sign one player up until midnight next Wednesday.
McInnes used the rule to sign Anthony O’Connor who made his debut in the loss to Fola.
Summer signing Miles Storey is available to face Ventspils having been ineligible for the first round. His contract at Swindon expired after that final deadline for the first qualifying round.
McInnes said: “We have Miles available for the next round but there would still be a possibility we could add someone to the list.
“It is not something that is imminent but I will not say that it will definitely not happen.”
