Hearn to unveil latest signing
Matchroom will announce their latest signing at a press conference at the Intercontinental Hotel on Park Lane on Tuesday.
Promoter Eddie Hearn is especially excited about his latest capture, which follows hot on the heels of world champion Ricky Burns and super-middleweight prospect George Groves.
"It's a huge announcement and potentially the biggest signing we've made in recent years," said Hearn.
"That's saying something with the likes of Froch, Groves and Burns added to the stable - but this guy has the potential to become a megastar."
Hearn has been keen to add some flavour to the occasion by keeping mum - while speculation continues over if and when Olympic gold medallists Anthony Joshua and Luke Campbell decide to join the paid ranks.
Other names being bandied about include lightweight Kevin Mitchell and heavyweights Dereck Chisora and David Haye.
The announcement will be made at 12.30pm.
