(JUNE 2) On May 29, 2015, WBAN published a  press release concerning an upcoming  Unified World Title on June 6, 2015.
Irma Balijagic contacted WBAN and stated the following:

"I would like to say a few words about the upcoming fight that was announced between Elina Tissen vs. Irma Balijagic ADLER.
 
With all my respect to Team Elina Tissen, but this fight was not even supposed to happen.

The truth is that Elina's coach/manager Mr. Maiki Hundt contacted me in regards to  if I would like to fight Elina Tissen, and I gave my answer as a positive but never had gotten any respond from Mr. Hundt.   I considered that as we won't be fighting.

Not long after I found out the fight was announced on Boxrec (without my knowledge).  I then contacted Mr. Hundt and got an email which said, "it was a mistake between me [Mr. Hundt] and matchmaker."

Which implies that I, Irma Balijagic did not canceled the fight (as it says in all German press) thatthe fight was never really set between two of us... Which also means that Elina's opponent is NOT a  quick replacement for Irma.  Thank you."
