Former UFC light heavyweight Thiago Silva will not be able to compete against Mike Kyle at this weekend's World Series of Fighting 22 in Las Vegas.
This Saturday night marks one of World Series of Fighting's biggest shows to date, but they had to make yet another last-minute changes to one of the feature fights on the card. When Mike Kyle was first booked for the show, it was against kickboxing standout Tyrone Spong. That fell through when Spong was injured, so controversial ex-UFC contender Thiago Silva was tabbed as his replacement.
