The 35-year-old defends his strap for the first time on November 17 after beating Lucian Bute in Mat to become a three-time world champion.
And after being the bookies’ outsider against Bute the tables have turned on the Cobra, who is the overwhelming favourite against Philadelphian Mack.
But Froch has insisted he will take nothing for granted as he prepares to meet Mack at Nottingham’s Capital FM Arena.
“I’ve got nothing to win and everything to lose,” Froch said.
“From that point of view I’ve got to keep myself focused and keep that determination and desire strong to make sure that when I’m in the gym I’m doing the work and when I’m hitting the punchbag, really gritting my teeth and putting in the work.”
Meanwhile Mack revealed he has no concerns about dropping half a stone to secure his shot.
“I’m going to stick to my gameplan and do what I’ve got to do,” he said. “Froch is an A-grade fighter, he comes to fight. But on November 17 he’s going to be in front of a real fighter who isn’t going to fade.”
