Cheick Kongo and Paul Buentello are all set to clobber one another in a heavyweight bout that has fireworks written all over it.

The two will duke it out during UFC on Versus which has been set for the Odeum Arena in Broomfield , Colorado on March 21. The main portion of the card will be the first UFC event to air live on the Versus network.

Buentello will be looking to keep his spot in the UFC following a decision defeat in his December return to the promotion at the lengthy hands of Stefan Struve, while Kongo finds himself in a somewhat similar position on the heels of consecutive defeats to the likes of Cain Velasquez and Frank Mir.

UFC on Versus will be headlined by a light heavyweight showdown between Jon Jones and Brandon Vera, while featuring other match-ups of Junior dos Santos vs. Gabriel Gonzaga, Anthony Johnson vs. John Howard and more.
