Michael Sprott will return to Prizefighter on November 14 after joining Team UK vs Team USA in the knockout tournament.
The Reading veteran beat Matt Skelton in the final of the fourth heavyweight edition back in October 2010.
However, he has a score to settle with heavyweights from across the water after losing out to American KO king Tye Fields in the Prizefighter International Heavyweights in May 2011.
Sprott joins Hackney's Larry Olubamiwo, Milton Keynes' Matt Legg and Hertfordshire's Tom Little in Team UK.
USA will be led by three-weight champion James Toney, who will be joined by Californian Damian Wills, former world cruiserweight challenger Brian Minto and Florida's Jason Gavern.
Olympic Gold medal hero Anthony Joshua MBE faces Croatian Hrvoje Kisicek in his third pro fight while cruiserweight prospect Ben Ileyemi meets Moses Matovu in his second pro outing.
