"The King of the Ring" will return to the MMA cage at World Series of Fighting 22 on Aug. 1 in Las Vegas, WSOF executive vice president Ali Abdel-Aziz told MMAFighting.com on Tuesday. The three-sport star's opponent is yet to be determined, but he'll be competing for WSOF for the first time since August 2013.
Spong (2-0) is best known for his GLORY exploits -- he's one of the best kickboxers in the world. The Suriname native also won his first two pro boxing matches back in March. Spong has been recovering from a broken leg he sustained during a GLORY fight with Gokhan Saki in April 2014.
