Report: BJ Penn vs Rory MacDonald will be the main event of UFC on Fox in December

Well that came out of nowhere.

When Rory MacDonald went down with a fluke cut which forced him out of his UFC 152 fight against B.J. Penn last week, many thought that the UFC would be looking for a suitable replacement. Several fighters offered their services including Afghan slugger Siyar Bahurdazada.

Apparently the UFC had bigger plans.

Last night during Spike TV's MMA Uncensored Live, co-host and former UFC middleweight Nate Quarry revealed that, according to his sources, not only is Penn vs. MacDonald still going to happen, it's going to be free on national television.

"And we have it on good authority, my insider has told me, that [Rory MacDonald vs. B.J. Penn] has been set for the Fox card in December. So we're gonna get that fight."

Now that's the type of main event on Fox that we've been hoping for.

Penn originally announced his retirement after receiving a beatdown from Nick Diaz at UFC 137, but the possibility of facing one of the brightest young talents in the UFC's welterweight division brought "The Prodigy" back.

Since his return, Penn has feuded with former opponent Jon Fitch, but he'll be hoping to put that behind him as he now has a new date set against "Ares."

MacDonald is coming off a devastating victory over Che Mills and has looked increasingly dominant in his last three fights, also scoring victories over current lightweight number one contender Nate Diaz and solid welterweight veteran Mike Pyle. Having a fight in December should give him more than enough time to recover from one of the most gruesome cuts in recent memory.

Is this the type of star power that you want to see on a UFC on Fox event?

Opinions, please.
