Spong has not fought MMA since his second professional fight against Angel DeAnda in 2013. In his last kickboxing bout, he suffered a fractured leg against Gokhan Saki at Glory 15. In MMA, Spong holds a 2-0 professional record. In kickboxing his record currently stands at 74-7-1.
Heun has twice tried to get a spot on “The Ultimate Fighter.” Both times he failed to win his fight to get into the house. The former University of Hawaii football player joined WSOF in 2014 and has gone 2-1 in the promotion. In his last fight, he scored a third-round arm-triangle-choke submission over Davin Clark at WSOF 22.
Williams will mark his WSOF debut against Heun. The Georgia native is 7-2 as a professional with two knockouts and three submissions. In his last outing, he scored a third-round shoulder-choke submission over Jared Hatch at SteelFist Fight Night 38.
In the main event of WSOF 26, featherweight champion Lance Palmer will look to defend his title against Alexandre de Almeida.
