Bellator officials announced the title fight on Friday. The televised event will take place at the Reno Events Center.
Minakov (13-0) won the title in November in a first-round TKO over fellow Russian Alexander Volkov. The undefeated 28-year-old cruised through the Summer Series Bellator tournament last year and has recorded stoppages in 12 of his 13 pro fights.
The Frenchman parted ways with the UFC in 2013, following a seven-year run with the promotion that encompassed 18 fights. Kongo never fought for a UFC title.
