The Promise: MMA Fighter Primary Care Giver for Father

(PRESS RELEASE) -- Rad Martinez is a 32-year-old Mixed Martial Arts fighter who has been told he must train 24/7 to reach the sport's highest stage -- the UFC. However, five years ago, he committed virtually every waking hour to another life course when he promised his dying grandmother he would take over as primary caretaker for his brain-damaged father. Martinez, a former All-American wrestler from West Jordan, Utah, was encouraged to give the MMA a try by his former Clarion University teammate Frankie Edgars, who is ranked the No. 1 MMA lightweight fighter in the world. After taking up the sport three years ago, Martinez has won nine of 11 matches. Outside the Lines presents the unforgettable story of a son's love, told through his very own words.

"He never got to see me wrestle in college. He never got to see me wrestle at all. I think if he were well, and didn't have brain damage, I think he would want to see that so I'm going to show him." -- Rad Martinez, on why he shows tapes of his fights to his father even though he may not grasp what he's watching

"It's ironic, when you step into the cage maybe, well some people would think, well now your caged in, but the real cage is at home. Stepping into that cage and fighting is kind of like taking off the shackles, unleashing a freedom. All of a sudden he's got a life, he's got freedom, he's got space." -- Levi Martinez, on the freedom his older brother Rad feels when he fights

"Everybody says the exact same thing:Wow, I don't know if I could do that. That's funny to me that people say that because I kind of know that a lot of people could do it. My grandma did it until she died. I'm going to it until: A. My dad gets better; B. My dad passes away; or C. I pass away." -- Rad Martinez, on the reaction he gets from people who learn of his story
