Glenavon 0-1 Donegal Celtic
Glenavon remain rooted to the bottom of the Premiership table, without a win, after this defeat by Donegal Celtic.
Ryan Henderson was twice denied by Andy Coleman in the first half, Mark Haughey and Peter McCann went close and Kevin Kelbie headed wide.
Henderson hit the winner on 61 minutes after being set up by Paul McVeigh.
After the game, Glenavon boss Martin Quinn dispensed with the services of his assistant Jeff Montgomery and first-team coach David Dorrian.
"David and Jeff will no longer be working with me," revealed under-pressure Quinn, who has appointed former Donegal Celtic manager Pat McAllister as his assistant.
"It's a very hard decision (but) sometimes these hard decisions have to be made in football.
"I have to thank Davy and Jeff for the very hard work they have put in at Glenavon but I feel it's time to change and regenerate ourselves."
Quinn added that the club could not "stoop any lower than we've done (today)".
And while in addition to the missed first-half chance, Glenavon also had a penalty claim turned down, the Lurgan Blues could have lost by more as keeper Coleman again excelled with saves from Darren Murray and a Jonny Harkness free-kick.
Coleman saved from Henderson early on and soon after Mark Miskimmin was through on goal, but he passed to Kelbie, who was quickly closed down.
Donegal Celtic move up to fourth position in the table with this away win.
