Pound-for-pound king and junior bantamweight world titleholder Roman "Chocolatito" Gonzalez (46-0, 38 KOs), who was the first fighter from Nicaragua to win belts in four weight classes, will be the subject of HBO's "2 Days" documentary series, the network announced on Wednesday. HBO's cameras followed Gonzalez for the two days leading up to his decision win over Carlos Cuadras to win a 115-pound title in September. The show will debut at approximately 1 a.m. ET/PT, immediately following the David Lemieux-Curtis Stevens card on March 11 and will also be a useful marketing tool heading into Gonzalez's next fight when he defends against Thailand's Srisaket Sor Rungvisai (41-4-1, 38 KOs) on the Gennady Golovkin-Daniel Jacobs HBO PPV undercard on March 18 at Madison Square Garden in New York.
