UFC on FOX 9: Nate Diaz accuses UFC of paying p---ys for 'bitching out' of every fight

Online mixed martial arts (MMA) gurus are the first to point out when someone is wrong about something.

I don't have much explaining to do when it comes to what Ultimate Fighting Championship (UFC) lightweight stalwart Nate Diaz was implying when he decided to tweet what was on his mind late Sunday night.

Bitching outta everyother fight now? wonder what that's like? #urpayingthesepussys

Enough said, right? Who could he possibly be referring to?

While injuries are common in the dangerous sport of MMA, one recent boo boo that stands out as the likely subject of Diaz's vague blurb would be the knee injury suffered by Anthony Pettis (more on that here). While I can't be 100-percent sure, I can point out the facts:

1. The younger of Stockton, California's two favorite brothers resides in the same weight class where Pettis is currently champion. While Diaz's next fight will take place at The Ultimate Fighter (TUF) 18 Finale and be a rematch of a split decision loss he suffered to Gray Maynard at UFC Fight Night 20, he is reeling after consecutive defeats at the hands of two fellow lightweights directly linked to Pettis.

The first being Ben Henderson, (UFC on FOX 5) -- victim of the infamous "Showtime Kick" and the man who carried the title until he met Pettis again at UFC 164. The second of Diaz's losses came at UFC on FOX 7 (via head kick) from the former Strikeforce champion who Pettis was scheduled to tangle with next.

2. "Showtime's" injury was initially said to not be bad enough to cancel his first title defense against Josh Thomson at UFC on FOX 9 on Dec. 14, 2013 from Sleep Train Arena, in Sacramento. But news broke during on Sunday that his bum knee would postpone the main event and that Demetrious Johnson vs. Joseph Benavidez will now headline.

3. The whole "bitching out of every other fight now" section of Diaz's tweet could be in reference to a prior injury Pettis experienced in preparation for a fight at featherweight which never saw the light day. He was supposed to scrap with Jose Aldo, but a similar knee issue altered UFC 163.

Nick Diaz and his younger brother Nate pull no punches when it comes to expressing what is on their minds. But following a Twitter suspension following some not-so-politically correct remarks, Diaz took the coy route this time.

Could this lead to a fight between the two at some point down the line? Pettis once said "it would be an easy payday.

Only time will tell, but one thing is for sure: Pettis' knee, T.J. Grant and a crowded title picture will have some say first.
