The Liverpool fighter said that he is fully focused on beating the 2000 Olympic gold medallist, who weighed in over a stone lighter than his fight against Ali Adams in May.
Price, who brings a unbeaten 13-fight record, revealed his delight at Harrison's svelte physique for their domestic dust-up.
"If Audley Harrison wants to retire if I beat him, that's his choice," said Price. "I'm completely focusing on my performance on Saturday.
"I'm delighted to hear that Audley has had a great training camp and he has a renewed spirit. I'd gain no satisfaction whatsoever beating up on him like David Haye did.
"I want him to come and fight and provide value for money for fans and that's what I'm going to do."
Price is making the second defence of his Lonsdale strap.
