Former division champion B.J. Penn will welcome former Strikeforce 170-pound kingpin Nick Diaz back to the Octagon this Saturday night (Oct. 29) at the Mandalay Bay Events Center in Las Vegas, Nevada.
Chael Sonnen's conspiracy theory notwithstanding, it's widely believed the winner of this weekend's headliner will be next in line for a shot at the winner of St. Pierre vs. Carlos Condit, who throw down for the UFC welterweight title in early 2012.
But let's not put the cart before the horse.
We still have a fantastic match up in "Sin City" first, between two foes who are very closely matched in most of their offensive and defensive skill sets. So who do the bookies like at the end of the night?
Let's take a look.
Our capital comrades over at Odds Shark have pegged "The Prodigy" as a slight favorite over Diaz at -130, leaving the Stockton slugger as the +100 underdog.
Diaz is on a ten-fight winning streak with nine finishes. Penn is 6-3-1 (across his last ten) and his only win over the last two years was a 21-second stiffening of fading legend Matt Hughes.
Fans of the Hawaiian will argue he's faced better competition. Detractors will call his body of work as a 170-pounder underwhelming, at best.
Who makes a better case for UFC 137? And more importantly, do these odds and betting lines compel you to plunk down some coin?
