Regian Eersel looks set to headline ONE Fight Night 21. The Dutch fighter has established himself as one of the leading standup specialists on the roster and will be defending his lightweight kickboxing title against promotional newcomer Alexis Nicolas on April 5th.

Eersel has won nine fights out of nine since signing for ONE Championship. He holds the lightweight kickboxing and Muay Thai titles and will be putting the former on the line next month.

Nicolas makes his official promotional debut but it is not his first time fighting on a card promoted by Chatri Sityodtong. At ONE Friday Fights 47 he beat Magomed Magomedov by decision.

Submission grappling

This will be one of two title fights on the card. The other will feature submission grappling with Tye Ruotolo putting his welterweight belt on the line against Izaak Michell.

This bout was originally announced for ONE 166 in Qatar. It got put back five weeks following a reshuffle which meant the Australian had to wait a little bit longer to make his promotional debut.
