Referee Mark Courtenay is the subject of a Portadown complaint

The Ports have questioned Courtney's performances in all their games in which he has officiated this season.

They include last Saturday's 3-1 defeat to Cliftonville in the JJB Sports Irish Cup quarter-finals.

Portadown have highlighted a number of incidents to the IFA, including the allowing of Cliftonville's second goal in the Solitude tie.

The club argue that their keeper Kevin Pressman was fouled in the build-up to the goal, allowing Gary Kennedy's free-kick from wide to go directly into the net.

Earlier this season Courtney awarded a penalty against the Ports for handball against midfielder Michael Collins.

Portadown claimed video evidence was available to show Collins was not guilty of the offence.
