Kilmarnock manager Kenny Shiels praised referee Stevie O'Reilly after the officials corrected their mistake in allowing Dundee an early goal in a 1-1 William Hill Scottish Cup fourth-round clash.
O'Reilly initially awarded Steven Milne's effort in the 15th minute but, with the Dundee players back in their own half awaiting the restart, O'Reilly then gave a free-kick for offside after consulting with assistant Charlie Smith, who had left his flag down.
Shiels said: "It takes a good person to admit when they're wrong and they did that. It was hard to see what colour of shirt it was in the sun. I couldn't see what happened but seemingly he was well offside."
He added: "I don't know how they established that but they had a discussion and one of them took charge of the situation and I felt that was very, very good by the officials. If it had been the other way around, maybe I would have another view."
Dundee's Matt Lockwood was not so impressed with the decision-making skills of the officials, although he accepted the right decision was made.
"I didn't go over myself but a few of the boys were saying the explanation didn't make sense," the Dundee left-back said. "I think the linesman didn't see it (the flick-on), the ref did see it. We asked why he didn't blow straight away if he saw he was offside.
"But they have gone on and had a conversation and if the ref is asking the linesman what he thought and the linesman didn't see it, it is a little bit odd.
"But they made the right decision in the end I suppose."
Lockwood looks set to give up penalty duties after Bell held his weak 64th-minute effort.
"I just changed my mind right at the last minute and probably took the worst penalty of my life," he said. "I'm bitterly disappointed. I hadn't missed a penalty for six years and I've missed the last three."
