Khan tackles policeman in 'Beat The Star'
The series sees members of the public go head to head with celebrities for the chance to scoop £50,000. The money rolls over to the following week if the star wins.
Khan, who is currently unbeaten in 17 bouts, will face Plymouth officer Dan Ivey in challenges ranging from physical and mental to more quirky tasks.
Avey, who works out five times a week and has won a police bravery award, remained confident when he learned the identity of his opponent.
He said: "I'm always up for a challenge and I know that I'll be up against somebody who thinks they can beat me. However this is going to be different. It's not boxing training, it's different events and different sports in this show so it's a challenge for me and I want to go out there and see what it's all about.... I'm definitely going to win, there's no doubt about it!"
Khan admitted that his fear of heights had left him dreading a challenge involving climbing a 10m telegraph pole, saying: "Stand on that for 30 seconds? I'd rather do 12 rounds with Mike Tyson."
The series, hosted by Vernon Kay, begins Sunday at 6.45pm on ITV1.
