Enzo Maccarinelli is set to make his return to the ring on 28 June, BBC Sport Wales understands.
The Welshman suffered a major career setback in March when he lost his WBO cruiserweight crown to David Haye.
An opponent and venue has yet to be confirmed, but fellow Welshman and former world champion Gavin Rees is in line to face Amir Khan in September.
Rees, 27, lost the first defence of his WBA light-welterweight title to Andreas Kotelnik in Cardiff in March.
But he is on a shortlist to take on Olympic silver medalist Khan, 21, for the Bolton man's Commonwealth lightweight title.
An official announcement of Khan's opponent is expected on Tuesday.

Former British super-featherweight champion Michael Gomez and Scotland's Ricky Burns are also thought to be in contention to meet the Olympic star.
Rees's fellow Enzo Calzaghe-trained stable-mate Bradley Pryce will defend his Commonwealth light-middleweight title in the chief support bout in Birmingham.
Khan had targeted a showdown with Rees before the Newbridge man's loss to Kotelnik - the only blot on his 28-fight career - as he said he was eager to claim the WBA crown.
Khan has won all 17 of his fights, with 13 knock-outs, and would tower seven inches above the 5ft 3ins Rees.
But the Welshman has upset the odds before, his defeat of Souleymane M'Baye for the WBA title in July 2007 stunning the boxing world.
