There are a few things that may be worth looking into in regards to February 15th card held in Bangkok. Fahsai Sakkreerin's bout with Van Bantilan may have been a non-title bout. Fahsai holds the IBF Pan Pacific title at 126 pounds and, according to an article by Ray Wheatley (see below), plans on defending it in March.
Fahsan (also spelled "Fashung") 3K Battery's opponent is in question. BoxRec has him beating Filipino Roldan Malinao while Mr. Wheatley reported 3K Battery pounded out a clearcut 8-round decision over Jason Butar Butar of Indonesia.
The article also lists results from the undercard.
