A lightweight match up between Gleison Tibau and Caol Uno is expected to take place at UFC Fight Night 21 on March 31 from North Carolina. Here's what Tibau had to say about the fight, courtesy of TATAME.com:

"Challenging legends of the sport is every fighter's wish, because you can grow in your career... I feel better to be back to the training heading to my biggest dream, the UFC title."

Tibau (20-6) is coming off a unanimous decision victory over the recently released Josh Neer at UFC 104. The American Top Team product is known for being one of, if not the largest lightweights in the UFC, having to cut as much as 30 pounds to make weight.

That size advantage will likely play a key role in the bout with the smaller Caol Uno (27-12). Uno, best known for his classic wars with Rumina Sato under the Shooto promotion, has only been victoriuos once in his last five fights. His last fight against Fabricio Camoes at UFC 106 was deemed a majority draw.

UFC Fight Night 21 is set to serve as the lead-in for The Ultimate Fighter 11, and is expected to be headlined by another lightweight match up between top contender Kenny Florian and UFC newcomer Takanori Gomi. Stay tuned to MMA Mania for more details on the card as they are announced.
