Institute's place in the Irish Cup quarter-finals has been confirmed after the Irish FA rejected an Ards protest.
Ards lodged an objection, claiming they were not notified of a late change to Institute's team sheet after Oisin Devlin's inclusion in the substitutes.
Devlin then came on at half-time as Institute won 1-0 at the Brandywell.
However, the Irish FA said on Thursday night that its Challenge Cup committee had "unanimously agreed not to uphold the protest".
The IFA's decision means the Londonderry club will have home advantage for their last-eight tussle with Linfield on Saturday, 2 March.
