It’s been a difficult past two years for Vivian Harris. Boxing politics coupled with long stretches of inactivity have plagued the former junior welterweight champion, but the proud Guyana native remains undeterred.

“I still consider myself one of the best fighters in the division,” said Harris. “I have faced some adversity these last two years but I’m still determined. I’m still hungry. I am here and I will be champion again.”

The 30-year-old Harris landed in Mexico City on Tuesday for his scheduled clash with Lucas Matthysse Saturday night at the Foro Scotiabank. Harris understands how important this fight is for his career. The winner puts himself right in the mix in the ultra talent-rich junior welterweight division.

“I’m ready to go,” said Harris Wednesday evening. “I’m fully prepared for Matthysse. This is my first step back to a world title and I will not be denied.”

The undefeated Argentine puncher Matthysse has compiled an impressive record of 25-0 with 23 KOs. His clash with Harris however, represents a significant step up in class, as thus far, his perfect record has come against mostly soft opposition.

Harris vs. Matthysse will be the co-featured bout with the Ponce De Leon vs. Orlando Cruz main event.

The card will air live in Latin America on the HBO Plus service.
