Merv 'the Mad Man' Mulholland has vowed to give Chris 'Da Badman' McDonald a knock-out retirement present tomorrow at the Ramada Hotel in Belfast.
The two MMA fighters headline Clan Wars 22 in what will be a rematch of a bout that took place in 2011.
Back then, McDonald believed Mulholland had no ground game and took the younger man to the mat. It was all over 20 seconds later as the Antrim fighter forced McDonald to tap from an armbar.
In the four years since their first meeting, neither man has seen their fortunes rise as much as they might have hoped.
Mulholland is only 24 but turned pro aged 18 and while still ranked ninth in the Irish welterweight division, he was expected by many to be a UFC star by now.
"I've been unlucky with injuries and had some heartbreaking defeats but now I'm at a stage where I'm so well drilled by my coaches that I can guarantee victory against Chris," said Mulholland.
"I know he's a good fighter but I'm younger and quicker - I'm sending him into retirement with a knock-out."
For his part, McDonald acknowledges the skills Mulholland possesses. He said: "I didn't think he had any ground game at all so I had no worries taking him down, but I got caught. It is true that this will be my last professional fight and I want to go out on a high."
With both men coming off the back of two losses, neither wants to make it a hat-trick, and with a large crowd to impress, this has all the makings of fight of the year in the welterweight division.
