After winning the GBU and WIBF world titles in 2010-2011, Tissen was declared the Unified Womens World champion when the World Boxing Federation (WBF) launched its cooperation with the WIBF and GBU last March, and merged the three championships into the most prestigious title in female boxing.
After nine years as a professional, 28-year old Tissen is 18-2 (6), and will be entering her twelfth championship fight against the two years younger Busa, who is a late replacement stepping in for Bosnian Irma Balijagic Adler to fight for her first title.
Busa, who actually has so far never boxed professionally in her native Hungary, only brings a 3-2 (1) pro ledger, but was an accomplished amateur and proved her worth when she stopped former world title-challenger Bettina Granasi in three rounds in her most recent outing.
Her two defeats were on points against good opposition, one of them in Serbia against undefeated Nina Stojanovic who is herself challenging a Unified World title on May 30, and Busa believes she can capitalize on this great opportunity and pull the big upset in Dortmund.
Billed as Hohensyburger Boxnacht, the Elina Tissen vs. Gabriela Busa Unified Womens World Featherweight title fight will be promoted by MiBo Boxpromotion.
