Trainer Peter Fury believes former opponent Steve Cunningham will help Tyson Fury sharpen his skills for his heavyweight clash with David Haye.
Fury's training is intensifying ahead of next month's showdown with Haye, live on Sky Sports Box Office, and Cunningham has agreed to spar with the unbeaten 25-year-old at his base in Belgium.
The American waged a thrilling war with Fury in April and floored the Wilmslow man heavily in the second round, before being knocked out by a big right hand in the seventh.
Cunningham, like Haye, is a former cruiserweight world champion with a similar build and Peter Fury believes the sparring sessions will be excellent preparation for the blockbuster bout on September 28.
He told World Boxing News: "Steve Cunningham is over here this weekend and we look forward to having him.
"Steve will bring his boxing skills, movement and speed with him and will be good for Tyson. I have always said that he is a top fighter and I am very much looking forward to meeting him when he gets here."
Eddie Chambers, a former heavyweight world title challenger, is also expected to arrive in Fury's camp later this month.
But Peter Fury could not shed any light on reports that Haye will spar with exciting US prospect Deontay Wilder as part of his preparations.
"I've no idea on Haye sparring with Wilder, but yes, Eddie Chambers said he would be here on the 21st and we are just waiting on confirmation," he said.
