Massage therapist Towey will be a part of Parker’s team for his big heavyweight fight against Derek Chisora on Saturday May 1.
Towey said: “I’m really happy to be working with Joe, he’s a top 10 fighter so I’m really pleased he wants me as part of the team for the fight coming up against Chisora.
“Joe is the fifth world champion I’ve worked with now, so I’m pleased with how things are heading after a tough 2020 as I think it was for everyone.
“I’m just looking forward to seeing some boxing again.”
