Yordenis Ugas was a huge favorite to beat Mike Dallas Jr., but FS1’s telecast of their main event Saturday night drew the cable network’s highest rating for boxing in five months.

Nielsen Media Research figures released Tuesday noted that a peak audience of 355,000 watched the Ugas-Dallas fight. That four-fight show, headlined by Ugas’ technical knockout of Dallas after the seventh round, drew an average viewership of 324,000.

That made this telecast of low-profile fights FS1’s most-viewed boxing broadcast since August 24. The main event of that show, Brandon Figueroa’s fourth-round stoppage of Javier Chacon in a 122-pound championship match, attracted a peak audience of 421,000.

On Saturday night, Cuba’s Ugas (25-4, 12 KOs) dominated Dallas (23-4-2, 11 KOs), of Bakersfield, California, in a welterweight fight that was scheduled for 12 rounds. Dallas’ handlers decided after the seventh round that he shouldn’t continue at Beau Rivage Resort & Casino in Biloxi, Mississippi.

FS1’s 90-minute “PBC Fight Night Prelims” show drew an average audience of 205,000 viewers from 6:30 p.m. ET until 8 p.m. ET.

That two-fight offering aired before the main card began at 8 p.m. ET. It featured an action-packed, 10-round cruiserweight fight, which Deon Nicholson (13-0, 12 KOs) won by unanimous decision over Earl Newman (10-3-1, 7 KOs).

Earlier Saturday, two Premier Boxing Champions preview shows produced solid Nielsen numbers on FOX.

The debut of the second episode of “Inside Wilder vs. Fury II” averaged 467,000 viewers from 4:30-5 p.m. ET. It was followed by the premiere of a “PBC Countdown” show, which averaged 508,000 viewers from 5-6 p.m. ET.

FOX, FS1’s parent station, is available in approximately 35 million more American homes than FS1.

Deontay Wilder (42-0-1, 41 KOs) and Tyson Fury (29-0-1, 20 KOs) are set to meet in a 12-round rematch February 22 at MGM Grand Garden Arena in Las Vegas. The second bout between Alabama’s Wilder, the WBC heavyweight champion, and England’s Fury, the lineal heavyweight champion, will headline a four-fight joint pay-per-view venture between FOX Sports and ESPN.
