Teiken Promotions won Tuesday’s purse bid to promote an IBF bantamweight eliminator between Ryosuke Iwasa and Sergio Perales for the right to face titleholder Randy Caballero.

Teiken bid $72,100, 60 percent of which ($43, 260) goes to Iwasa, with 40 percent ($28, 840) going to Perales, according to IBF Championships Chairman Lindsey Tucker.

“We have to have the contracts within the next two weeks, so I didn’t get anything yet,” said Tucker. “But I’m 99 percent sure that the fight is going to happen in Japan, I just don’t know the date.”

A southpaw from Kashiwa, Japan, Iwasa (18-1, 11 knockouts) has won 10 straight fights, five of them by knockout since being stopped in the 10th round by RING No. 1-rated WBC titleholder Shinsuke Yamanaka in March 2011. Iwasa, 24, was last in action for September’s second-round knockout of journeyman Rommy Wasser.

A 27-year-old from Brownsville, Texas, Perales (24-2, 16 KOs) is 4-2 with four knockouts over the course of his past six fights. Also a left-hander, Perales, 27, was stopped in the second round by Caril Herrera in September 2011, and lost by unanimous decision to Stuart Hall in May 2013.

The 24-year-old Caballero (22-0, 13 KOs) earned the title with a hard-fought unanimous decision over Hall in October.
