Ultimate Fighting Championship (UFC) is slowly but surely filling up its upcoming pay-per-view (PPV) fight card scheduled for Nov. 17, 2012 at the Bell Centre in Montreal, Quebec, Canada.

UFC 154, headlined by a welterweight title unification bout between reigning champion Georges St. Pierre and 170-pound Interim titleholder Carlos Condit, will also get some heavy leather thrown in the light heavyweight division when Chad Griggs drops down to 205 pounds to tangle with Cyrille Diabate.

UFC officials announced the pending match-up earlier today.

Griggs (11-2) was making a career out of playing spoiler, pounding out Strikeforce heavyweight prospects Bobby Lashley and Gian Villante, as well as seasoned veteran Valentijn Overeem in consecutive bouts. Unfortunately, the grass isn't always greener on the other side, a lesson he learned at the hands of Travis Browne earlier this year in Atlanta.

If at first you don't succeed, drop a few pounds and try again.

Diabate (18-8) has failed to make any kind of significant progress inside the Octagon following his ZUFFA debut in early 2010. "The Snake" is 3-2 in the wake of his majority decision win over Tom DeBlass back in April, but has yet to string together consecutive wins under the UFC umbrella.

And don't expect the power-punching "Grave Digger" to make it easy for him.

UFC 154: "St. Pierre vs. Condit" will also feature a welterweight bout pitting Martin Kampmann vs. Johny Hendricks. The winner is widely-expected to face the winner of St. Pierre vs. Condit for the UFC 170-pound title later this year, or perhaps in early 2013.
