Curtis Allen struck the decisive goal at Windsor Park last night as Glentoran staged a sensational comeback against Linfield to book a Europa League play-off final scrap with Cliftonville.
The Glens battled back from 2-0 down with Allen completing the fightback just a few hours after receiving clearance to play following a successful appeal against a red card.
Linfield are angered by the Irish FA's disciplinary call on Allen and this Euro shocker, which denies them a shot at a £200,000 cash windfall, increases the pressure on manager David Healy who raged afterwards: "I told the players that some of them will be leaving the football club."
The Glens, with Ronnie McFall still in temporary charge, will now face Cliftonville at Solitude on Saturday (3pm) in the play-off final after the Reds cruised to a 4-0 win at home to Ballymena United.
There were scenes of celebration at the Belfast Loughshore Hotel Arena where Newry secured four promotions in five seasons after winning 3-1 at Carrick Rangers, sealing a 6-3 success on aggregate.
A club that was forced out of business just six years ago will now be back in the top flight next season.
