Texas' Bubba Bush enters the Octagon for the first time tonight on the heels of a four fight winning streak against Kevin Casey, a dangerous jiu-jitsu black belt from the legendary Rickson Gracie with three consecutive wins since his last Octagon appearance.

Guilherme Vasconcelos returns to action, seeking his fourth pro win in his UFC debut against Luke Zachrich, who took the long road to the Octagon after his stint on TUF 7.

Turning pro in 2011, Rob Font has become a fixture on the New England fight scene and after nine straight wins, he steps into the Octagon to meet George Roop, winner of three of his last four, and as his knockouts of Chan Sung Jung, Josh Grispi, and Brian Bowles showed, he could end the fight at any moment.

Brazil's Bruno Santos is fired up and eager to put together another winning streak like the 13-fight run that opened his career. Middleweight prospect Chris Camozzi has been impressive in his UFC career thus far, proving that he's ready for the next level in the 185-pound weight class, and that quest starts with a win over Santos.

Ildemar Alcantara may have found his true fighting home at 170 pounds, but now he will test his ground game against Kenny Robertson, former college wrestler who has become a dangerous man on the mat, and in his first Las Vegas bout in over three years, he's looking forward to another finish.

Unbeaten in his last five bouts, Alex Caceres is ready for the biggest fight of his career against Urijah Faber, who has finished four of his last five wins, and as he approaches the matchup with Cacares, 'The California Kid' wants to show his opponent that there's no substitute for experience.
