Martinez will lead the procession of floats in the 123rd Rose Parade on Monday, Jan. 2, 2012. The former "All My Children" star will also toss the coin before kickoff of the 98th Rose Bowl Game in honor of all wounded military personnel.
"J.R. Martinez is an inspiration to us all and a natural fit for our theme Just Imagine...," said Rick Jackson, president of the Tournament of Roses. "J.R. is not only a courageous and engaging role model for us all but has dedicated himself to helping not only servicemen and servicewomen, but all Americans facing challenges."
Martinez said he's grateful for the opportunity to share his message of hope and possibility.
He said ever since he was injured in Iraq, he's tried to stay positive because when you stay positive, good things will happen.
Martinez was deployed to Iraq in March 2003. During his deployment, he was severely burned when his Humvee hit a land mine in Karbala. Three other soldiers were ejected from the burning vehicle, but Martinez was trapped inside. He suffered smoke inhalation and severe burns to 40 percent of his body.
After spending 34 months in recovery and undergoing 33 different surgeries, Martinez became a motivational speaker, traveling the country to meet with other injured soldiers.
