Murray enjoyed success as an amateur, winning the ABA welterweight title in 2004, despite a troubled time away from the ring, including serving four spells in prison.
The St Helens native has since turned his life around, going pro in 2007 and putting together 23 straight victories under the tutelage of trainer Oliver Harrison.
His first assignment was a points success over Jamie Ambler in Wigan, before tasting mainstream acclaim at the Prizefighter Middleweight tournament in November 2008.
He saw off Joe Rea, Danny Butler and Cello Renda - the first by unanimous decision, the other two by split decisions - in three-round contests on the same night to earn the £25,000 prize.
It was a unanimous verdict over veteran Australian Peter Mitrevski Jr in July 2010 that earned Murray his first belt, the Commonwealth middleweight title.
He added the WBA intercontinental strap four months later with a third-round TKO of Carlos Nascimento and defended it in April 2011 by stopping another Brazilian, John Anderson Carvalho, in four rounds.
The British middleweight title became part of his collection in his most recent outing, the previously undefeated Nick Blackwell's corner pulling their man out after five rounds.
And the 29-year-old will now take another step up in class to challenge for Felix Sturm's WBA middleweight title.
