'Cowboy' Cerrone packing lunch for three rounds of ‘hell’ against Anthony Pettis, while 'Showtime' gets reinjured

There doesn't seem to be any love lost between current Ultimate Fighting Championship (UFC) lightweight contenders Anthony Pettis and Donald Cerrone.

"Cowboy" recently called out "Showtime," telling the Roufusport fighter to stop crying about his shoulder and quit being a "bitch ass." Those words didn't sit too well with the "pissed off" former World Extreme Cagefighting (WEC) 155-pound champion, issuing a warning to Cerrone that he better be prepared to back up "all the 'mess' he's been talking."

Though the two have yet to be booked for an event, the belief is, according to "Cowboy," the two scrappy lightweights will square off sometime in December or January. Cerrone recently told MMA Interviews he has already signed his part of the deal and he is just waiting for Pettis to do his part, which is to heal his shoulder and sign on the dotted line.

He explains:

"I'm looking forward to that fight. Hopefully December we're gonna get it, beginning of January. My side of the deal is signed. (I'm) just waiting on him while his shoulder is rehabbed. There's been a lot of shit talking back and forth, so it's gonna be fun. It's gonna be for the fans. I think it's gonna be Fight of the Night for sure. He's well-rounded. I think my wrestling is better than his but if we go to the ground he's good on the ground, if we stay standing he's good there. It's gonna be a helluva fight. I'm packing a lunch. I'm ready for three rounds of hell. I'll fight him on an undercard, I don't care."

Cerrone's patience might wear just a little bit thinner as Pettis took his his Twitter account earlier today to reveal yet another setback because of injury:

"Can't catch a break injuries fucking suck!!!"

Details are slim as two how severe his latest injury is; however, it seems it might be enough to delay the "Cowboy" showdown a bit longer.

Both are currently enjoying two-fight win streaks, with Pettis coming off a first round knockout victory over Joe Lauzon at UFC 144 and Cerrone putting his former training partner, Melvin Guillard, to sleep at UFC 150 in little more than one minute.

Though the two are no slouches on the ground, Pettis and Cerrone have a knack at wowing fans on the feet, as evidenced by their previous performances.

If and when the two lightweight contenders match up, it is sure to be filled with fireworks, as well as have major title shot implications on the line. The victor will set himself up nicely to be next in line to face the winner of current champion, Ben Henderson, and number one contender, Nate Diaz, as they prepare to headline UFC on FOX 5 on Dec. 8, 2012, which will go down at KeyArena in Seattle, Washington.

How about it Maniacs, who is your early pick to prevail in this potential "Fight of the Night" barnburner between "Cowboy" and "Showtime" when it finally goes down?
