Nick Diaz will likely fight Jay Hieron at Strikeforce’s August 15 event in San Jose after his original opponent, Joe Riggs, was hospitalized after reportedly suffering a bad reaction to an undisclosed drug and forced to withdraw from the bout.
Gracie Mag first-reported the likely replacement on Tuesday, adding that Phil Baroni was nixed by Showtime as a replacement for the fight and an agreement with Takanori Gomi could not be reached.
Strikeforce has not yet confirmed whether the newly-created Strikeforce welterweight title will still be on the line for the Diaz-Hieron matchup as was planned when Diaz was to square off in a rematch with Riggs.
Diaz (20-7) has won five-straight, including recent victories over Frank Shamrock and Scott Smith, while Hieron, who was to fight Paul Daley at the recently-canceled August 1 Affliction: Trilogy event, has also won five in a row, most-recently defeating Jason High via first-round knockout in January.
On Monday, a light heavyweight championship bout pitting title-holder Renato “Babalu” Sobral against Gegard Mousasi was added to the Showtime-televised event, which is headlined by Gina Carano vs. Cristiane “Cyborg” Santos, though a lightweight championship unification fight between Josh Thomson and Gilbert Melendez scheduled for the event could be scratched.
