Steve Cunningham fighting for more than career against Amir Mansour
"It's been a roller-coaster," Cunningham said. "I wish God could take my heart out and give it to her. But I'm putting this on me. I have to do this for my daughter. I feel if I can make as much money as I can, I can keep helping her. I have to win this fight. I need to win. My family, we need a win. Even if it doesn't turn out right, we are still going to be walking in faith."
