For those who haven’t been tuning in to watch the Ultimate Fighter Brasil 2 on a regular basis probably haven’t ever heard of William Macario or Leo Santos. That will change this weekend when the two talented Brazilians battle it out at UFC on Fuel 10 for the right to be named the season’s champion.

The 21-year old Macario is undefeated six fights into his career. Also impressive, all of Macario’s fights have featured a finish with all but one occurring inside the opening round of action.

Santos, a submission specialist, has more than 2X Macario’s experience and owns a 13-2 career mark. He has won nine of his last ten tilts including success in five straight.

Fans can catch Macario-Santos mix it up after the main card kicks off on Fuel TV at 8:00 PM EST.
