The Dons secured a third-place finish in the Scottish Premiership table last season, holding off a challenge from Dundee United for the chance of European football.
Derek McInnes's side recently enjoyed a 7-0 friendly win over Arbroath in their preparations for Thursday's fixture.
McInnes is likely to name a similar lineup that saw Aberdeen cruise to a comfortable victory over their fellow Scots.
Meanwhile, Riga are currently in the middle of their league season, where they sit in seventh position in the table.
