Strikeforce’s Aug. 15 event in San Jose, Calif. featuring the biggest fight in female MMA history between Gina Carano and Cris Cyborg was also supposed to be a history-making event in that it was going to feature four title fights.
However, after losing a heavyweight title fight between incumbent Alistair Overeem and challenger Fabricio Werdum due to Overeem re-injuring his hand, it appears that Strikeforce could be on the verge of losing a second title fight.
According to GracieFighter.com, a site owned and operated by the Cesar Gracie, the trainer of Nick Diaz, the rematch between Diaz and Joe Riggs in which the first-ever Strikeforce welterweight champion would be crowned is now off.
The report claims a bad reaction to a drug is the reason for the cancellation of the bout.
“Joe Riggs has pulled out of his fight with Nick Diaz after suffering a bad reaction to an as of yet undisclosed drug,” writes the site. “According to sources close to the fighter, Riggs will be recovering in the hospital for the next couple of weeks and therefore unable to fight Diaz. At this time it is unclear if Riggs’ problem is physical or mental.”
Strikeforce or Riggs have yet to address the report publicly but Gracie Fighter goes on to add that Diaz will remain on the card with a new opponent expected to be revealed over the course of the next several days.
