Boxer Daniel Jacobs, who survived rare cancer to become a world champion, announces retirement at 37

Earlier today, former middleweight boxing champion Daniel Jacobs announced his retirement from the sport at 37 years of age. While it's a formidable task to achieve a world title, 'Miracle Man' has fought and won a harder battle, surviving cancer.

The decision to hang up the gloves comes following his loss to Shane Mosley Jr. last week at the Honda Center in Anaheim, his second consecutive defeat.

At the time of retirement, Jacobs holds a professional record of 37-5 with 30 knockouts, and boasts wins against notable names such as Julio Cesar Chavez Jr. and Sergio Mora.

He has also locked horns with boxing greats Canelo Alvarez and Gennadiy Golovkin in title fights.

According to a report by ESPN, 'Miracle Man' was diagnosed with a rare form of bone cancer called osteosarcoma in 2011, which left him paralyzed. This, however, did not put an end to his pugilistic journey.

Jacob's spinal column was reconstructed after a successful surgery that removed a tumor wrapped around his spine. He then underwent multiple rounds of radiation treatment following which he made a triumphant return to the ring in a first-round TKO win over Josh Luteran in 2012.

Later in 2014, the American claimed the WBA middleweight title in a fifth-round TKO win over Jarrod Fletcher. He would then go on to capture the IBF belt in a split-decision win against Sergiy Derevyanchenko in 2018.

Announcing his retirement via Instagram, Jacobs wrote:

"Through the ups and downs, inside and out of the ring, I have managed to become [a two-time] world champion and I'm able to say I'm the first cancer survivor to be a boxing world champion, the biggest achievement I ever could achieve. Being able to inspire others with my story has always made me feel my life meant more than just fighting inside the ring. A true Miracle Man. Job well done. Job well done."
