Zlaticanin and Marsili have been initially put forward to fight for the interim belt following an injury to Jorge Linares, although it is thought that the victor will eventually be boosted to full status depending on the timescale.
Should Linares be unable to face the winner in the next few months, Zlaticanin or Marsili would then be recognised as champion and free to make their own defense of the coveted green strap.
At the same 135 pound limit, Franklin Mamani and Chad Bennett have already been approved to fight for the vacant silver title on April 30 in China.
Also on March 18, a super-featherweight title eliminator between Jul Giner and Miguel Roman will involve a purse bid, with the winner eventually going on to challenge Francisco Vargas.
Meanwhile, the WBC are set to make a ruling on the cruiserweight division imminently following the collapse of a mandatory contest between Grigory Drozd and Ilunga Makabu.
Drozd was ruled out of the April 8 Moscow bout through injury and the subsequent delay may force the WBC’s hand to at least offer South African-based Congan and mandatory contender Makabu an interim shot.
