Two lightweights will be looking to rebound after the first loss of their ONE Championship careers. Lowen Tynanes meets Pieter Buist in a bout that is set to be broadcast on April 28th (US time).

At ONE on TNT Part IV there will be an opportunity for Tynanes (10-1) to recapture the form that saw him win his first six ONE Championship fights. The Hawaiian has only fought two times in the last six years due to a combination of illness and injury.

Buist (17-5) saw his eight fight winning streak snapped by Timofey Nastyukhin, while Tynanes had won ten in a row before losing to Murat Gafurov. The Dutchman lost his spot in the top five after that defeat.

Also added to the card today was a flyweight fight between Colbey Northcutt (1-1) and  Sovannahry Em (4-1). Both are coming off wins with ONE Championship yet to crown a champion in this division.

In Muay Thai action former flyweight champion Jonathan Haggerty returns. He has been matched with Elias Mahmoudi, with the entire card set to be broadcast by TNT in the US.

As previously announced former middleweight champions Aung La Nsang (26-11-0-1) and Vitaly Bigdash (10-2) will both face off for the third time in the main event. This will be a non title rubber match, both men have won one of the previous two fights.

Shinya Aoki will be back in action at ONE on TNT Part IV. The former lightweight champion has been matched with UFC veteran Sage Northcutt.

Promotional newcomer Stephen Loman takes on a UFC veteran in a bantamweight bout. The former Brave 135lbs champion has been matched with John Lineker at ONE on TNT Part IV.
