Another one bites the dust.
Joe Riggs has been forced out of his upcoming rematch against Nick Diaz for the first-ever Strikeforce welterweight title at "Carano vs. Cyborg" from the HP Pavilion in San Jose, Calif., on Aug. 15.
GracieFighter.com reports that "Diesel" suffered "a bad reaction to an as of yet undisclosed drug" and "will be recovering in the hospital for the next couple of weeks."
The good news is that Diaz plans to still compete on the card; however, no possible replacement is known at this time. Of course, Riggs joins Alistair Overeem on the recently-scratched list for the promotion's upcoming event, which originally featured four championship bouts.
