The unseeded draw for quarter-final pairings was held on 5 November.[1] The tie between Rijeka and Osijek has been postponed for 2014 due to Rijeka's congested fixture list. Both clubs initially agreed to play the first leg in Rijeka on 12 February 2014 and the second leg in Osijek on 19 February 2014. However, due to the flooded pitch in Rijeka, the first leg was played on 19 February and the return leg in Osijek on 12 March.
