Given their competition level on the way up, it comes as a surprise that Yordenis Ugas and Abel Ramos haven't previously crossed paths.

The pair of no-nonsense welterweights both made weight for their secondary title fight which takes place Sunday evening at Microsoft Theater in Los Angeles.

Ugas clocked in at a fighting fit 147 pounds for his second attempt at a version of the welterweight crown. Ramos weighed 146 pounds for his first such title fight, which tops a special Sunday edition of Premier Boxing Champions (PBC) on Fox beginning at 8:00 p.m. ET.

Both boxers are fighting for the second time in 2020, a rare treat in a pandemic-stricken year where many of the sport's top players are still awaiting their first ring assignment.

Ugas (25-4, 12KOs) is coming off of a one-sided 7th round stoppage of Mike Dallas Jr. this past February in Biloxi, Mississippi. The win was the second straight for the 34-year old Miami-based Cuban, who scored a landslide decision win over previously unbeaten Omar Figueroa last July in his first fight following a heartbreaking 12-round split decision loss to then-WBC welterweight titlist Shawn Porter last March.

Ramos (26-3-2, 20KOs) enters on the heels of a literal last-second stoppage. The 29-year old from Casa Grande, Arizona was well down on the scorecards heading into the 10th round of his Fox-televised crossroads clash with Bryant Perrella, before scoring two knockdowns inside of the final minute. The latter of the two left Perrella defenseless in the eyes of referee Jack Reiss, who stopped the contest with just one second left on the clock.

The bailout knockout ran Ramos' current win streak to eight straight since suffering a 10-round majority decision defeat to Jamal James, now an interim welterweight titlist.

Ramos is joined on Sunday's telecast by his nephew, red-hot junior welterweight prospect Jesus Ramos (12-0, 11KOs). The 19-year old southpaw weighed 142.8 pounds for his Fox-televised showdown versus Brawley, California's Esteban Garcia (14-0, 6KOs), who weighed 142 pounds for their scheduled eight-round battle of unbeaten prospects.

Also on the show, Omar Juarez (8-0, 4KOs) returns for his second fight in four weeks. The Brownsville, Texas-based prospect weighed 142.8 pounds for a scheduled eight-round junior welterweight clash versus Dakota Linger (12-3-2, 8KOs) who tipped the scale at 144.4 pounds.
