Tomorrow’s Top Rank on ESPN main event between WBO junior lightweight world champion Jamel Herring and Jonathan Oquendo will not proceed as scheduled after Herring tested positive for COVID-19 earlier this morning.

For some fight fans this might come as a relief as Herring’s bout against Oquendo was met with little fanfare, as an astute fan would look at Oquendo’s size and see he is similar to Carl Frampton, the bout Herring has been wanting. Oquendo had also recently lost to Lamont Roach Jr, whom Herring recently beat.

The new main event will be Mikaela Mayerversus Helen Joseph at the junior lightweight division taking place Tuesday’s night (ESPN & ESPN Deportes, 9 p.m. ET).

WBO champ Herring had the following to say
“…I then retested on July 3 and my test was negative, so this result is a complete surprise. I was fully prepared to make my second title defense tomorrow night.”

In addition, the Luis Melendez-Eddie Vazquez bout has been canceled due to Melendez testing positive for COVID-19.

The ESPN telecast will continue as follows:

Main Event: Mikaela Mayer vs. Helen Joseph, 10 Rounds, Junior Lightweight
Clay Collard vs. Lorawnt-T Nelson, 6 Rounds, Middleweight
Ruben Cervera vs. Clay Burns, 6 Rounds, Lightweight
