A soldier who survived one of the bloodiest battles in Afghanistan and served in Iraq is now playing big-time college football.

Daniel Rodriguez, who has written a new book about his incredible journey, sat down with Elisabeth and Brian to talk about walking onto the Clemson University football team.

Rodriguez is now in his third year with the Tigers as a senior wide receiver after earning a Purple Heart, having been wounded in the Battle of Kamdesh in 2009.

Coach Dabo Swinney decided he would try to give Rodriguez a shot in 2012 after seeing a workout video that went viral.

Rodriguez recalled that it was a "humbling experience" to get the call from Swinney, adding that playing college football was a promise he felt he had to keep to one of his friends in the military.

"We were talking one day about what we wanted to do when we got out of the military. Just seeing as much combat as we had at a young age, we wanted something different. And he was killed in front of me. Mine was to go on and play college football somewhere, anywhere. I didn't know where I was gonna land," said Rodriguez.

In an awesome moment last season, Rodriguez scored a touchdown against The Citadel on Military Appreciation Day.

He's trying to share a message of "never give up" with veterans who are trying to make a successful transition back to civilian life.

"You come home and you feel lost in a world that doesn't understand you. A lot of people get depressed over that," he said.
