Mayo progressed to the FBD League semi-final after a penalty shootout win over Leitrim in Carrick-On-Shannon on Sunday.
The game finished 2-13 a piece at Páirc Seán Mac Diarmada after 70 minutes, after which it went straight to the penalties. Mayo won the shootout 4-1 and will face Galway next weekend.
Mayo manager James Horan told RTÉ that he discovered on Saturday that the game being decided on a penalty shootout was a possibility.
"Just in the World Cup," Mayo manager Horan told Mid West Radio when asked if he'd seen anything like it before.
The game was Horan's first of his second stint in charge of Mayo.
It was interesting. The guys struck them away pretty well.
Jason Doc won the toss and we had the first one, that put the pressure on [them]. It's much hard to score a penalty in Gaelic than it is in soccer. He stuck that one away and it put a bit of pressure on Leitrim.
"The game itself, we were very lucky to get away with a draw," continued Horan.
"Even though we were a point up four minutes into injury time, we were still very lucky to get a draw. Leitrim had a 15 minute period in the second half where they were all over us. We couldn't possibly make more mistakes if we tried to do it.
"Leitrim were very strong, well organised and probably should have beaten us today. We stuck in there an hung around and did enough good things to get through in the end.
"Some of the new guys, I was very happy with how they did. Overall, some of the scores we conceded today and some of the battles we lost were not good.
"We lost both throw-ins and from the throw-in, the ball was spilt on the ground. It was there for us to win, we didn't win it and they were through on goal within three or four seconds.
"That kind of thing is you're not going to develop too much if that kind of thing is happening. The amounts of attacks that went straight down the middle of our defence was shocking today."
