Spong (Dave Mandel/Sherdog)Tyrone Spong Injured, Clinton Williams Named Replacement Against Jake Heun at WSOF 26 José Youngs December 3, 2015 News, Spotlight, WSOF It looks like combat sports fans will have to wait even longer for Tyrone Spong’s return to mixed martial arts. On Wednesday afternoon, WSOF officials announced a injury has forced Spong out of his scheduled co-main event fight against Jake Heun at WSOF 26 in December. This bout was to mark pong (2-0 MMA, 2-0 boxing, 74-7-1, 1 NC, 46 KO’s kickboxing) first MMA bout since earning a decision over Angel DeAnda at WSOF 4 in 2013. Since then, the “King of the Ring” has been forced to watch on the sideline after suffering a grisly leg break in his kickboxing match against Gökhan Saki at GLORY: 15. He was expected to return to the WSOF cage this summer before a leg injury forced him postpone these plans. As a result of Spong’s injury, Heun (8-4) will now meet Clinton Williams in a preliminary card matchup. Heun (8-4) will be looking to pick up his second straight win under the WSOF banner after earning a third round submission win against David Clark at WSOF 22 in August. The 31-year-old Williams (7-2) has won four of his last five fights and is coming off a third-round submission of Jared Hatch last month at SteelFist Fight Night 38. WSOF 26 is scheduled to take place at the The Chelsea inside The Cosmopolitan of Las Vegas on Friday, Dec. 18. The main card will air live on NBCSN.
