Paris Fury is keen for him to take on Anthony Joshua in a unification bout before quitting the ring for good for the sake of his health.
Speaking to the Mirror, she said: “I’d like him to beat Anthony Joshua and then stop.
“He’s in the ring with supreme boxers and it is a dangerous sport. We both know the risks.
“I know one shot can change everything.”
Paris, who was born and bred in Doncaster to an Irish traveller family and tied the knot in her home town, hopes 31-year-old Tyson – who beat Deontay Wilder to take his WBC belt – can retire undefeated after proving himself one last time against Joshua.
She told how the couple, who have five children, have been trying to return to lead a normal life since his stunning victory.
“He’s done the school run, he’s taking the rubbish to the tip and he’s pottered around a bit in the garden. It’s all about trying to get back to normality,” she said.
She insists fame and glory haven’t changed him, adding ‘he even went on at me the other day for buying some fancy cushions’.
Paris also revealed the couple, who have been together for 15 years, are plagued by online trolls but try ignore them.
“I don’t read hateful comments. There’s so much bullying and hatred online. I’m not going to benefit from reading hate, so I don’t,” she told the Mirror.
