After an exciting start to the main event that saw Cyborg pick Carano apart with powerful punches, Santos used a late flurry of ground and pound to force the referee to step in and stop the bout just one second remaining before the end of the opening frame.

With the victory, Cyborg improves to 8-1 with eight-straight wins dating back to 2005, while Carano falls to 7-1 after suffering he first career loss.

In other main card bouts, Gegard Mousasi became the new Strikeforce light heavyweight champion with a 60-second knockout of Renato “Babalu” Sobral, Gilbert Melendez retained the promotion’s interim lightweight title with a third-round TKO of Mitsuhiro Ishida, and heavyweight contender Fabricio Werdum submitted Mike Kyle in the opening round to kick off the Showtime broadcast.

Fanhouse learned of the news on Monday afternoon from Ken Pavia, Hieron’s manager.

As reported earlier Monday, Diaz will be replaced on the August 15 “Carano vs. Cyborg” card in San Jose by one-time UFC fighter Jesse Taylor, who is currently riding a seven-fight winning streak.

Taylor and Hieron will meet in a three-round, non-title fight on the Showtime-televised card.

Stay tuned to MMAFrenzy.com for the latest Strikeforce news and Strikeforce rumors.

As MMAFrenzy.com reported earlier today, Diaz, who missed a scheduled Friday drug test, has until 3pm PT today to show up and submit a sample for the mandatory pre-fight screening before he’d be pulled from the fight. If Diaz makes today’s deadline, results from the test would be available on Thursday.

Diaz previously tested positive for marijuana in 2007, which caused his gogoplata submission of Takanori Gomi to be changed to a no contest, and was pulled from an EliteXC card last year due to his disclosed use of medical marijuana, but passed an April drug screening before his Strikeforce bout against Frank Shamrock.

Taylor (13-3), a finalist on The Ultimate Fighter 7, was removed from the finale following a drunken rampage in Las Vegas and went on to be cut by the UFC after suffering a first-round submission loss to CB Dollaway in his lone fight inside the Octagon. “JT Money” has since gone 7-0, most-recently defeating Dong Sik Yoon at DREAM 10 last month.

If Diaz fails to show for today’s test, Strikeforce is expected to announce the news and name a replacement to fight Hieron on the Showtime-televised card before the end of the day. However, if Diaz submits his sample in time, MMAFrenzy.com will pass along results from the test once they’re available on Thursday.

The recently-finalized card for the event is:

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.

Trilogy is headlined by a heavyweight matchup between top-ranked Fedor Emelianenko and Josh Barnett.

Also confirmed for the pay-per-view main card are Gegard Mousasi vs. Renato Sobral, Vitor Belfort vs. Jorge Santiago, and Paul Daley vs. Jay Hieron, as well as Paul Buentello, who is expected to take on the winner of a June 27 bout between Pedro Rizzo and Gilbert Yvel.

The fight card for Trilogy currently features:

PAY-PER-VIEW CARD

From Diaz’s trainer Cesar Gracie:

“With a title fight against Cung Le nowhere on the horizon Nick will probably be going back down to the 170lbs division. I know there’s been speculation about a rematch with Robbie Lawler, but Diaz will be dropping weight as he picks up his running and cardio training.

As far as a return to lightweight is concerned, forget it. Unless BJ Penn or some other mega fight comes up he won’t return to that weight class. It just isn’t healthy. He was having terrible performances against B-level fighters. The weight drop was causing lots of health related problems and he wasn’t performing to his ability. If you put Anderson Silva at lightweight he’d get crushed cause he’d enter the cage half dead. Now we got guys that are running around bragging about how good they did with Diaz when he was a lightweight.

After this fight we’ll have Nick drop back down to 170lbs and probably stay there unless Strikeforce has something interesting for him.”

In related news, IFL veteran Jay Hieron, a winner of four-straight including a first-round knockout of Jason High at Affliction: Day of Reckoning in January, recently told MMAjunkie he accepted the June bout with Diaz before Scott Smith was tapped for the matchup. According to Hieron, who was also offered a spot in the DREAM welterweight grand prix, he’s now likely to return at Affliction’s third show on August 1st or 15th.
