Ali Adams has claimed that Audley Harrison is "a joke" after the two fighters confirmed that they would meet on April 14.
Harrison hasn't stepped in the ring since his 2010 loss to David Haye and Adams believes that he can force the 40-year-old into retirement.
Adams said: "Audley is a joke. His fight with Haye was an embarrassment and he still wants to make a comeback.
"I will give him such a beating that Audley will see he does not belong in a boxing ring again."
The fight will take place at the Brentwood Centre.
