As a result of the disrupted build-up, Parker's camp requested the fight be shortened to six rounds, something Thompson, who has never fought beyond four rounds, readily agreed to.
"I had no problem when they shifted it to six rounds. I said, 'heck yeah, we can go four if you want'."
Thompson started his professional boxing career in 2005 but has fought only nine times. He took four years off to concentrate on MMA, which he said he enjoyed, and his eight years in the navy also took him away from the fight game. Thompson served on an aircraft carrier as a firefighter, a career he has continued outside the military, although he remains a reservist, serving one weekend a month.
He has fought twice over the past 12 months, for a win and a loss, but mainly puts his skills to use through sparring - he trained with undefeated American Deontay Wilder this week.
While he has been impressed with 22-year-old Parker, Thompson said the Kiwi had weaknesses.
"I think there are definitely opportunities to be able to beat him. He makes mistakes. No one has really been able to make him pay for it yet. He gets over-aggressive.
"I think he is beatable. He has been up against some pretty good competition but nothing great. Brian Minto is a tough guy, there's no doubt about that, and even the Brazilian [Marcelo Nascimento], he came to fight, he was tough. They are the two biggest names on his resume."
