Amateur star Oleksander Usyk continued the impressive start to his run in the paid ranks with a fourth round stoppage win over former world title challenger Epifanio Mendoza at the Ice Palace in Ukraine.
The 26 year-old southpaw made it two wins from two starts without a headguard and kept up his 100% KO rate against the experienced Colombian. Usyk stayed on the fast-track to even bigger bouts in 2014 after proving he is levels above despite having only fought twice as a professional.
Also on the bill, Klitschko sparring partner Vladimir Tereshkin is now 18-0-1 following a unanimous eight-round victory over veteran Oleksiy Mazikin, his third win of the year.
Southpaw Tereshkin, 25, rarely allowed Mazikin into the fight and was handed a 77-73 (twice), 77-72 nod by the judges as the 6ft 6ins beast moved on to considerably bigger challenges in the top division.
In other results, former interim world title challenger Sergey Fedchenko suffered a shock defeat at the hands of ten-loss Felix Lora, dropping his WBO European light-welterweight title to the Spain-based Dominican in the process.
Welterweight contender Viktor Plotnykov had no such trouble in his contest as he blasted out previously undefeated Valeriy Brazhnyk in the first round to score a 30th win from his 33 outings.
