Tyson Fury faces Derek Chisora for a third time on Saturday night when he defends his WBC heavyweight title.
Over 60,000 fans are expected to pile into the Tottenham Hotspur Stadium for the bout, which is scheduled to start no later than 9.30pm.
Inside and outside the ring, Fury is a big character but many may not be aware of his strong Irish roots.

The 34-year-old was born in Manchester, but his father John is from Tuam in Co Galway, while his mother hails from Belfast.
His grandfather is also from Tuam, Co Galway.
He previously held the Irish professional heavyweight title and represented Ireland as an amateur on three occasions.
Fury's family come from a traveller background - something he is hugely proud of.
He previously said: "I'm proud of what I am. I'll tell you what makes a traveller: you're born one like you're born black. To me it is irrelevant whether I live in a house, a caravan or a tent.
"I like the feel of being a gypsy. The traveller background gives you that ultimate fighting steel, the determination and will to win, to dig deep. There's no loser in me.
"As a traveller you never regret anything. You do what you have to do and move on. No ifs, buts or whys."
And after beating Wladimir Klitschko to become world champion in 2015, a delighted Fury beamed: "I’m the first Irish heavyweight champion of the world, me Tyson Fury."
Fury donned green shorts and gloves for his fight against Wilder in Los Angeles.
He once told Irish Central.com: “All my people are from Ireland. I was born in Manchester but I am Irish. I have lived in Ireland, visited all my life and when I fight I represent Ireland."
Fury is also a distant cousin of former WBO middleweight champion and Limerick native Andy Lee as their grandmothers were sisters.
He has fought in Dublin before, on the undercard of Bernard Dunne's last outing when he lost his WBA Super Bantamweight title to Prakorb Udomna.
He also fought in Belfast in 2018 when beating German Francesco Pianeta at Windsor Park on the undercard of Carl Frampton's win over Luke Jackson.
