Helenius, who is currently in his third reign as Continental title holder, first met Chisora back in December 2011 and came out on top in a highly controversial decision on home soil in Helsinki.
A big underdog at the time, Chisora seemed to take the front foot away from Helenius for the duration of the fight, although was robbed of a victory after the twelve rounds as the Finn kept his unbeaten run intact.
Since then, Helenius has won five on the bounce as the 31 year-old improved to 22-0, whilst in contrast, Chisora, 32, has lost three times at the very highest level to Vitali Klitschko, David Haye and Tyson Fury in a busy period of twelve fights.
Offers to stage a possible return have to be made to the EBU headquarters by noon on Thursday, January 21 following the removal of previous belt holder Erkan Teper under a hefty cloud.
Teper was suspended by the EBU for two years for two positive drugs test, and although it was thought Chisora was out of the running to face Helenius, bids were called for just over three weeks’ time – when more will become clear on the fight.
