Tommy Wright accused referee Don Robertson of wanting the final say as St Mirren dramatically moved into the last four of the Scottish Cup.
The Paisley outfit face St Johnstone in the semi-finals after an epic penalties win in Kilmarnock.
Saints looked out as they trailed 3-2 in the final seconds of extra-time, but referee Robertson adjudged Jake-Doyle Hayes to have been fouled by keeper Colin Doyle allowing Jamie McGrath to take the tie all way.
Jak Alnwick’s save from Rory McKenzie then put Saints through, but, while Dundee United came out of the hat against Hibs, Killie boss Wright was fuming at the whistler.
He said: “Let’s be honest, Don Robertson put it into penalties with a poor decision. When he is man enough he will own up to it.
“Over the years I have been in to see Don more than any other ref. He changed the whole game.
“We could have dealt with the situation better, but it is not a penalty all day long. The goalkeeper clearly gets the ball, the fact that it spills out is irrelevant. No penalty.
“But Don wanted to have the final say and he got it. We go out because of a poor decision.”
Wright’s was rocked by the pre-match loss of Kyle Lafferty to injury and, although he may return for the weekend Premiership game against Motherwell, his team also had to play almost all of extra-time last night with only 10 men after sub Nicke Kabamba sustained a knock.
Goodwin’s team also felt aggrieved at the award of an extra-time penalty against them when sub Kyle McAllister was deemed by Robertson to have fouled Brandon Haunstrup allowing Ross Millen to net.
But it didn't matter in the end, although the gaffer could barely celebrate at full-time after admitting he went through the wringer.
Goodwin said: “I think I’ve got about six months to live after that. I don’t know how much longer I can handle the stress.
“It’s huge relief. I felt it very hard to celebrate at the end the way I probably would in a normal situation.
“We made extremely hard work of it, but I’ve also got to give enormous credit to Kilmarnock.
“Tommy made the change bringing Kabamba, but then loses him minutes later.
“I sympathise with Tommy, but, thankfully, it was our night. Two semi finals in one season, it’s a great achievement for everybody.
“But no one will remember the performance in a couple of days time. St Johnstone will be slight favourites after they how went about the League Cup, but we’ll enjoy this and give the boys a couple of days off.
“I don’t want to see anyone until the weekend. I’m going to lie down and sleep for a couple of days.”
