Glentoran's reserve team have been stripped of the Steel and Sons Cup they won on Christmas Day after fielding an ineligible player in an earlier round.
The Glens beat Ards 3-0 in the final but it later emerged goalkeeper Carter Dawson should not have played in the fourth round win over Wellington Rec.
The Glens were docked seven lost league points over Dawson's registration.
The keeper was signed after the 31 August deadline and should not have played for Glentoran before January.
It means the Steel Cup, a competition for intermediate teams, is without a winner for this season - the first time this has happened since 1894.
Glentoran II manager Spike Hill resigned over the matter earlier this month.
