"I go like four weeks, where I go once a week and it's just a long day at the hospital getting chemo," Marshall said.
Marshall will head back to the hospital in the morning for chemotherapy. During spring practice a few years ago, he noticed pain in his ribs. That pain was caused by leukemia.
Marshall's fight with cancer meant he had to give up playing football for a while. But it didn't mean giving up being part of the team. He kept working hard, hoping to get back on the field and to serve as an inspiration for his teammates.
"If people didn't show up for summer workouts because they just didn't feel like coming, I'd try to be like, 'Well I had chemo today and I still came,'" Addison said.
Marshall's hard worked paid off. He played in the last half of the last game this past season for his Foster High Falcons. That hard work and determination led Marshall's coach to nominate him for the 2012 High School Football Rudy Award. It's named after Daniel "Rudy" Ruettiger, the Notre Dame football player who's life story inspired the movie "Rudy."
"I was so happy to win -- just shocked, just a mix of emotions," Marshall said.
Marshall's mom, Val Marshall, is very proud of her son's achievement and gives credit to the Foster High football team.
"I've just witnessed what football means to these kids and it's something you can't really articulate very well but I think that's one of the reasons he's here today, it's football," she said.
Addison Marshall beat out several finalists with similar inspiring stories and will receive a $7,500 scholarship. Doctors give the teen a 50-50 shot at beating cancer. This kid seems like a big favorite to beat those odds.
