A middleweight matchup between Tim Kennedy and Evangelista “Cyborg” Santos has been announced to headline a September 25 Showtime-televised “Strikeforce Challengers” event at the SpiritBank Event Center in Tulsa, Oklahoma.

Middleweight Wilson Gouveia has withdrawn from his UFC 102 matchup against Ed Herman after suffering a back injury that will sideline him until at least October.

MMA News first reported the injury on Friday just days after Herman was tapped to replace an injured James Irvin and take on Gouveia at the August 29 event in Portland.

More light as now been shed on rumors that M-1 Global may have misled Gegard Mousasi in negotiations with the UFC before the light heavyweight signed with Strikeforce as CBS Radio host Carmichael Dave recently spoke to UFC Vice President of Talent Relations Joe Silva on the subject of Mousasi and M-1, and later posted a transcript of that conversation to the Sherdog Forums:

“Gegard called me about a week ago. He asked if it was true that the UFC offered 40/40 (40k to show, 40k bonus to win), Silva said. “I told him no, because we never actually made an offer. Not only did we not make an offer, but we would’ve assumed his Affliction contract and its terms. So whatever Affliction was paying him, that’s what we would’ve honored, and it was considerably more than 40/40.”

Edith Labelle is out as one of the UFC’s Octagon Girls, replaced by Natasha Wicks (pictured), who won the Octagon Girl search at UFC 100 last month.

“Something happened,” Labelle’s manager James Leinhos told Fanhouse of his client’s departure from the UFC on Friday, “but at this time, I can only confirm that Edith no longer works for the UFC.”

A middleweight matchup between Dan Miller and Aaron Simpson, which was first reported early last month, is now back on for UFC Fight Night 19 after a fight between Simpson and Ed Herman was scratched from the card when Herman was tapped to replace an injured Jame Irvin at UFC 102 earlier this week.

All 22 UFC 101 fighters hit the scales on Friday at the Wachovia Center in Philadelphia to weigh in for their Saturday bouts, and the entire card, including headliners BJ Penn, Kenny Florian, Anderson Silva, and Forrest Griffin, successfully made weight.

The UFC lightweight champion Penn and challenger Florian both tipped the scales exactly at 155 pounds, while UFC middleweight title-holder Anderson Silva and Forrest Griffin both weighed in at 205 for their light heavyweight matchup.

All 22 fighters set to be in action tomorrow at UFC 101: Declaration, including headliners Anderson Silva, Forrest Griffin, BJ Penn, and Kenny Florian, will hit the scales today to weigh-in for Saturday’s matchups.

Though no major announcements were made during a Strikeforce conference call or UFC press conference on Thursday, the animosity between the promotions was clear. Strikeforce co-promotion partner M-1 Global expressed its distaste for the UFC and the way it treats fighters, while UFC President Dana White said Fedor will put “Strike-farce…out of business”.

M-1 Global’s recently-announced “Breakthrough” event, which was to take place on August 28 at the Los Angeles Convention Center, will apparently take place at another location to-be-determined after the promotion declined to approach the California State Athletic Commission about the card.

According to SI.com’s Josh Gross, the event is now likely to take place at a venue to-be-announced in Oklahoma.

The UFC will hold its final pre-fight press conference today at 1pm ET/10am PT in Philadelphia for Saturday’s UFC 101 event, which is co-headlined by Anderson Silva’s return to the light heavyweight division to take on former champ Forrest Griffin and lightweight title-holder BJ Penn defending his belt against Kenny Florian.
