A triumphant return for the coach of the indianapolis colts. After a personal battle off the field, today we witnessed his return to it. Reporter: The head coach of the indianapolis colts, chuck pagano, already facing heavy odds when the season started, fresh off an awful season last year. The fans wondering where have all the good times gone. Then that diagnosis. The 52-year-old coach had leukemia, forced to leave the team for treatment. As he fought off the field, the team was fighting on it, turning that record around, making it to the playoffs, while back at the hospital, the coach recalling the moment doctors told him he could go home. Dr. Craig came in and we had a conversation. He said, your counts are starting to come up a little bit. I said how are they? He said good enough to go home. And so you're like -- it's like a day early. So, anyway, he said what time's the game? And I said we play 1:00 today. So it was big. It's awesome. And today their prayers answered. The coach was back. He was undergoing treatment -- from the stands, those chants, we want chuck. There were hugs on the field and then the team performed. One of the biggest thrills of the game, the unbelievable run the entire field, the coach and his colts winning.
