After coming in a pound overweight Monday, Joseph Adorno never made it to the scale Tuesday in Las Vegas.

The 21-year-old lightweight was supposed to weigh in a second time Tuesday afternoon, but Adorno felt ill and withdrew from his scheduled eight-rounder against Alexis del Bosque. ESPN was supposed to televise the Adorno-del Bosque bout as part of a five-fight telecast from MGM Grand Conference Center in Las Vegas.

Adorno (14-0-1, 12 KOs), of Allentown, Pennsylvania, officially weighed in at 136 pounds Monday, one above the contracted maximum. Dallas’ del Bosque (17-5, 9 KOs) stepped on the Nevada State Athletic Commission’s scale at 134¼ pounds.

Their teams made an agreement with the NSAC that Adorno couldn’t weigh more than 142 pounds at another weigh-in Tuesday afternoon. Adorno didn’t weigh in a second time because he was sick.

Adorno-del Bosque was the second fight ESPN and promoter Top Rank lost Tuesday afternoon, though it wasn’t related to a failed COVID-19 test. Jamel Herring, the WBO junior lightweight champion, revealed on social media that he tested positive for the coronavirus last week and that his title defense versus Jonathan Oquendo has been postponed indefinitely.

The 12-round, 130-pound title bout between Herring (21-2, 10 KOs) and Oquendo (31-6, 19 KOs) was supposed to headline ESPN’s show July 2 from MGM Grand Conference Center.

Without Adorno-del Bosque, ESPN will proceed Tuesday night with a four-fight telecast.

The show will start at 8 p.m. ET/5 p.m. PT with Puerto Rico’s Christopher Diaz (25-2, 16 KOs) and Jason Sanchez (15-1, 8 KOs), of Albuquerque, New Mexico, in a 10-round featherweight fight. In the 12-round main event, Australia’s Andrew Moloney (21-0, 14 KOs) will defend his WBA world super flyweight title against San Antonio’s Joshua Franco (16-1-2, 8 KOs).

ESPN will broadcast two six-rounders between the Diaz-Sanchez and Moloney-Franco fights.

In one of those bouts, Miguel Contreras (10-0, 6 KOs), a junior welterweight from Bakersfield, California, will meet Milwaukee’s Rolando Vargas (5-0, 5 KOs). Also, Phoenix-based heavyweight Adam Stewart (8-0-1, 5 KOs) will battle Helaman Olguin (7-3, 3 KOs), of South Jordan, Utah.
