The UFC could be on the verge of putting together a battle between big-name welterweights, as former top contender Josh Koscheck announced via Twitter on Wednesday night that he has been offered a fight with former two-division champion BJ Penn, and has accepted it, pending the agreement of "The Prodigy."

Whether that agreement will come, however is anyone's guess.

In a recent appearance on The MMA Hour, Penn, whose recent 1-3-1 stretch has dropped his lifetime record to 16-8-2, was noncommittal on a return to the cage. His last bout, a unanimous decision loss to Nick Diaz at UFC 137, put the thought of retirement into Penn's mind, and it still seemed quite present earlier this month.

"I don't know," Penn said. "I'm enjoying training right now and you never know what the future holds. I mean if Dana put something together and says, 'Hey, you want to do this?' You never know what could happen. Being a competitor, you always have that itch. What it is, is that it's tough. The training camps are tough going and through that and going through the different things and all the different personalities you gotta deal with over time....It's just a tough question and I can't give any solid question (answer) either way right now."

Koscheck, meanwhile, is coming off of a split decision loss to Johny Hendricks at the UFC's event on Fox on May 5, his second loss in four bouts. That dropped his career record to 17-6, and combined with his 0-2 record against UFC Welterweight Champion Georges St-Pierre, figures to keep him out of the title picture for the foreseeable future. That being the case, the highly visible Koscheck is best served by taking the biggest fights he can get, and a battle with Penn, one of the biggest stars in UFC history, fits the bill just fine.

Koscheck is a year Penn's senior, although when you listen to Penn's thoughts on a possible retirement, he definitely sounds older. Of course, Penn has been in the sport since the age of 21, while Koscheck turned 27 the year he stepped into the cage for the first time, so it's natural to think of Penn as the more veteran of the two fighters. And not every veteran is up for hanging around on the "legends circuit" once the possibility of being the best of the best is gone. Randy Couture did it longer than most, while Chuck Liddell all but went out on his shield. Penn - who also turned down a fight in Strikeforce with lightweight champion Gilbert Melendez - seems to think more like Couture, but we won't know for sure until Penn answers the challenge.
