For the Ukrainian it will be the fifth defence of his title since beating SamuelPeter in October 2008 to regain the WBC crown, having temporarily retired in 2004.
Between the two of them, the list of the people they successfully fought includes Lennox Lewis, Danny Williams, Corrie Sanders, Chris Areola, Sultan Ibragimov, Calvin Brock, Lamon Brewster, and SamuelPeter.
Cairney's game was quickly brought to an end when he was replaced with veteran Simon Donnelly just before Samuel made way for Saints team-mate Peter MacDonald.
