Popular New York City-based junior middleweight Captain Boyd “Rainmaker” Melson will be featured on HBO’s Real Sports on Tuesday, April 16, at 10 p.m. ET/PT.

Melson, 31, donates his entire fight purses to Justadollarplease.org in support of a trial to help cure chronic spinal cord injuries.

Melson boxes for his “soul mate,” Christan Zaccagnino, who was paralyzed from the neck down in a diving accident at age 10. Melson donates his money toward the hope that one day, medicine will discover a way for Zaccagnino to walk again.

A West Point graduate, Melson maintains a grueling schedule to train while working a typical 9-to-5 office job. Real Sports correspondent Frank Deford visits with Melson and Zaccagnino to learn more about their tale of love and devotion.

Melson (10-1-1, 4 KOs) will face Troy Lowry (28-12, 17 KOs) on the April 27 undercard of a Showtime-televised main event featuring Philadelphia’s Danny Garcia RING junior welterweight title defense against ex-beltholder Zab Judah at Barclays Center in Brooklyn.

Melson was last in the ring at Barclays Center last Oc tober, where he battled Jason Thompson to a draw on the undercard of Garcia’s fourth-round knockout of Erik Morales.
