The all-female strawweight cast of The Ultimate Fighter 20 hasn't been in Las Vegas more than a week and there are already reports of possible disciplinary action being dolled out.

"I'm very excited," UFC president Dana White said Sunday evening. "It's like nothing we've ever done before. We have the top 16 women in the world in that weight class and it will crown a champion at the end of the season. It's different, it's exciting, it's new. The women go after it. The first day when they get in there, there's already been stuff. Half of them don't like each other. It's going to be a very interesting season."

White was then asked by a media member if he could confirm a rumor that cast member Felice Herrig was nearly thrown off the production the very first day of shooting.

"Well, I wouldn't say she almost got thrown off, but a fight broke out the first day," said White.

Herrig most recently dropped a one-sided decision loss to fellow cast mate Tecia Torres in December, but the strife more than likely involved her longtime rival Heather Clark. Herrig and Clark have flung insults at one another for years, but the pair were infamously involved in a post-fight scuffle at Bellator 94. Having lost a split decision and being taunted by Herrig, Clark reportedly backhanded her opponent with the arm she actually broke during the bout. Then in December 2013, signed under the Xtreme Fighting Championships (XFC) banner, Clark was scolded by promotion president John Prisco for tweets she made disparaging Herrig, going as far as to say she could be released from the promotion.

Coached by lightweight champion Anthony Pettis and No. 1 contender Gilbert Melendez, the 20th installment of the reality series is due to air this fall.

End Of An Era, Thank You B.J. Penn For Everything

Yesterday, we witnessed the end of the legendary career of B.J. Penn when B.J. returned after a 18 month layoff. B.J. got the opponent of his choice in Frankie Edgar because B.J. had lost twice to Edgar. This time it was different because B.J. had to drop to 145 pounds in order to fight Edgar and B.J. agreed. On Saturday during the weigh , B.J. looked like he had not problem making 145 and during those weigh in, B.J. had the most support from the crowd. Unfortunately this is where the story is going to have a terrible ending. The fight yesterday did not live up to the hype of B.J. returning. What we saw from B.J. was another athlete that lost their fight with father time. At no point in the fight did I have I feeling of, yes B.J. has a chance. What I saw instead was a dominant performance from Frankie Edgar and sealed the fate of the legendary career of B.J. Penn. ...
