Harrison will pack punch on TV, says manager
The ambitious 28-year-old Glaswegian has dreams of unifying the division before doing the same at other weights to build his profile.
Calzaghe's lucrative super-middleweight unification fight with Jeff Lacy had been arranged for next month but a hand injury scuppered those plans.
Harrison will step in and appear on terrestrial television when he defends against Nedal Hussein at the Braehead Arena on November 5.
Harrison's manager Frank Maloney said: "It was bad news Joe Calzaghe got injured but we weren't going to pass this opportunity up. He wouldn't have fought until February so he jumped at the opportunity to get back in the ring earlier."
Australian Hussein, 27, boasts a staggering 14 first-round knockouts 20 stoppages inside three rounds in a 41-fight career. But Maloney is convinced he will beat the challenger in front of the ITV cameras and earn the respect of the English fight fans who have ignored his achievements so far.
"He doesn't get the credit he deserves. If he was from London or Manchester he would seen as one of the best fighters and get a lot more credit," Maloney said.
Maloney believes his next fight could be against dangerous Dominican Republic featherweight Joan Guzman.
The 29-year-old, who was the WBO super-bantamweight champion before moving up a division, is rated seventh in the world and was installed as Harrison's mandatory challenger with a win over Terdsak Jandaeng in August.
Maloney believes that match-up would finally see his man crack America and put himself on the world map.
"His next fight could be a mandatory fight with Joan Guzman. That would put Scott on the world map. In America they would say: 'Who is this Scottish boy? He is the real deal and he has got to be taken really seriously.'"
