Lisnagarvey coach Mark Tumilty is having to learn the ropes the hard way after being red-carded just a few games into his new role.
But the former Irish international player is determined that the setback won't affect his long-term plans.
And he insists that he, and indeed umpires, can learn from what happened during the Kirk Cup derby clash which decided Pool D on Saturday.
It was Garvey who beat Banbridge in their own backyard, a 3-2 win putting them into the semi-finals alongside holders Cookstown, league champions Annadale and Instonians.
The draw will be made at the Ulster Branch meeting on Thursday evening.
But Tumilty admits that the red card coming so early in his new coaching career doesn't look good, and that he's going to have to try and button it along the line, even if he feels there is something positive to be said.
"It wasn't a particularly dirty game, but there were two red cards and a couple of yellows which perhaps give the wrong impression," he says.
"I regret the red card, but am not sure that I did enough to provoke it," he added.
"I didn't swear, nor was I aggressive but I felt that the game was in danger of getting out of control and told the umpire."
Banbridge captain Scott McCandless also saw red, and he was a bit unlucky in that Bann were given a 'team yellow card', which is a weapon umpires can use to bring the game under their control. But as soon as he made a rash tackle on Mark Robinson, the yellow became red.
The first half was scoreless but all the talking points came in the second, with Bann taking the lead through David McAnulty and then falling behind to goals from Mark Raphael and Jonny Bell.
Ross McCandless levelled matters but Brian Waring snatched a late dramatic winner.
Colin Donaldson scored the only goal of the game for the Tyrone men against Bangor to ensure they keep a grip on the trophy.
Although coaches Geoff Hamilton and Michael Haycock would have liked to have seen more goals, it was particularly pleasing that they were the only team to go through their three pool games without conceding a goal.
William Annett scored his fifth goal of the season for Kilkeel but it wasn't enough to stop Annadale going through, the Belfast lads winning 3-1 with brothers Neil and Ian Hamilton on the mark as well as Fraser Mills.
But it's still Colin Barnes who is the top scorer after he added another two to his tally as Instonians saw off Mossley.
Next week it's the league programme which kicks in, and all eyes will be on that clash between Annadale and Garvey at Jordanstown.
