The 34 year old Shumenov began his career in 2007 and was fast tracked to a Light Heavyweight title, winning a hugely controversial decision over Gabriel Campillo for the WBA Light Heavyweight title in his second shot. Ever since that win he has has a somewhat frustrating career, with a string of poor title defenses, against the likes of a shop worn William Joppy, a limited Danny Santiago, and a hopeless Tamas Kovas. After losing the WBA Light Heavyweight title in 2014, to Bernard Hopkins, Shumenov moved up in weight and in May 2016 he would claim the WBA Cruiserweight title to become the first 2-weight world champion from Kazakhstan. It's worth noting that he hasn't fought since that title win, and he'll have been out of the ring for over 24 months byt the time he faces Altunkaya.
As for Altunkaya he made his debut back in October 2008 and was a very well managed fighter, winning his first 29 fights without taking on an opponent of any name recognition. In June 2017 he stepped up in class and was stopped by Krzysztof Glowacki, who forced Altunkaya to retire at the end of round 5, following a very 1-sided contest. Since that loss he has fought once, scoring his 30th win against a no-name foe this past January.
It should be noted that this will be for the WBA's "regular" world title, and not the and not the highest version of the title, which is held by the "Unified" champion Murat Gassiev. Just to muddy the waters even more the WBA have a "champion in recess" in Denis Lebedev and an interim champion, Arsen Goulamirian. Resulting in an astonishing 4 WBA champions!
Also confusingly the current rankings list the inactive Shumenov as the #2 ranked fighter and Altunkaya, who has beaten no one of any note, at #3.
The bout will take place in Astana, Kazakhstan, and is expected to show case a number of top Kazakh hopefuls.
