In 2011, American boxer Daniel Jacobs was diagnosed with a life-threatening form of bone cancer, and was partially paralyzed. Told he would never walk again, Jacobs defied the odds by becoming WBA world middleweight champion in 2014. Drew Hallowell/Getty Images North America/Getty Images
Jacobs praised his coach Andre Rozier (second from the right) for standing by him through his recovery. "This was the hardest challenge in my life and I couldn't do it alone," Jacobs says.

Rozier started coaching Jacobs when the boxer was 14, and was immediately impressed. "I saw the changes in maturity and his growth. I said, 'He is going to be a really good fighter,'" recalls Rozier.
As a talented youth boxer, Jacobs was named the "Golden Child". After overcoming cancer he received a new nickname -- "Miracle Man." Pictured, Jacobs works out at Gleason's Gym, in Brooklyn. Cliff Hawkins/Getty Images North America/Getty Images

Rozier says he has a father-and-son relationship with Jacobs. "[Rozier] taught me a lot about how to be man," Jacobs says. "He means the world to me."

Rozier is known for his no-nonsense training style and his passion for the sport. "I live, sleep, drink this sport of boxing," he said.
