Aberdeen face a battle to keep Euro hopes alive
Rijeka 2 Aberdeen 0
Aberdeen face an uphill task to progress in the Europa League after losing 2-0 in Rijeka.
Second-half goals from Antonio-Mirko Colak, a penalty, and Robert Muric undid good defensive work by the Scottish Premiership side - who go to St Mirren in the league on Sunday - in their third qualifying round tie.
The Dons - who had won 3-0 at Rijeka in the second qualifying round four years ago - created few chances on a cagey night in Croatia.
Shay Logan grabbed Colak's shirt after 61 minutes when there appeared little danger with the penalty duly converted.
Muric further tilted the tie Rijeka's way two minutes from time with a splendid low shot from 20 yards.
Scott McKenna lined up at the heart of the Aberdeen defence despite being unsettled at Pittodrie.
The Scotland international had handed in a transfer request earlier this week amid interest from Championship sides Nottingham Forest, QPR and Sheffield Wednesday.
