Heroic Jamie Conlan climbed off the deck twice to overcome tough Mexican Junior Granados in Dublin on Saturday night.
Conlan was floored by a vicious body shot in the seventh round but managed to beat the count.
A flurry of punches from Granados eventually downed Conlan moments later, but again the Belfast fighter rose to his feet and survived the round.
Conlan went on to win a unanimous decision 95-93, 95-93, 96-92 to retain his WBO Inter-Continental Super Flyweight title at a raucous National Stadium.
He was also crowned new WBO Intercontinental champ.
It was a huge scare for the 28-year-old who moves his record on to 14-0 (8 by knockout).
“I’m glad it’s over now because it was a tough one,” said Conlan, who was also rocked by a big shot in the fourth round.
“I made a lot of mistakes in there tonight. A fight like that means you have to go back and learn from your mistakes but tonight I proved that I have another weapon in my arsenal.
“I proved I had courage and that nobody is going to come in here and beat me easy. They’re going to have to earn it.
“Fights like that are good to watch but you can’t go through six or seven of them in your career. I want to make nights easy for myself and have a long career.
“I knew this was going to be a tough fight and a lot of questions were going to be asked of me. Tonight I had the answers.”
