Inverness defender Gary Warren says watching his team-mates suffer shoot-out agony in the League Cup Final was the worst moment of his career.
The English centre-half was forced to watch the match from the Celtic Park stands after he was sent-off as the Highlanders broke Hearts in the semi-final.
It turned out to be an excruciating experience as Warren watched his team first battle through 120 minutes of goalless action before Billy McKay and Greg Tansey failed to score from 12 yards as the Dons snatched the trophy with a 4-2 win.
Warren said: "It was horrible to watch. It was the worst thing I have had to do in football.
"I was sitting in the stand knowing I couldn't do anything to help the lads.
"I was probably more nervous in my seat than I would have been out there on the pitch.
"But I can't fault Danny Devine who came in for my place. He was outstanding and it's such a shame he has ended up on the losing side."
McKay saw Inverness' first spot-kick saved by Dons keeper Jamie Langfield while Tansey ballooned his high over the bar.
But Warren insists the two penalty sinners should feel no shame.
"The two lads are fine," he said, ahead of Wednesday's Scottish
Premiership clash with Motherwell. "They are both tough characters. It would have hurt on the day and they feel like they have let everyone down.
"But they haven't. They have been outstanding all season and without them, we would never have got to the final.
"Billy has been brilliant for us for the past two years, while Greg Tansey's goal in the semi was a big contribution too.
"They are model professionals and they know life goes on. They will be looking to get back on it against Motherwell and I'm sure they will."
Fifth-placed Inverness will ease some of their pain at Fir Park in midweek by closing the six-point gap separating them from a Europa League slot.
"We have to put Sunday to one side and move on," said Warren. "Sunday was a day that no-one will ever forget.
"We didn't get the right result but now we have got a big game against Motherwell that we need to focus on."
