Adam Kownacki came in a little lighter than he did for his last fight and everyone else required to make weight did exactly that.

That’s what happened Friday afternoon during the New York State Athletic Commission’s official weigh-in for the “PBC on FOX” tripleheader Saturday night at Barclays Center in Brooklyn.

Keith Thurman and Josesito Lopez weighed in exactly the same, at 146½ pounds, for their 12-round, 147-pound title fight at Barclays Center. The 30-year-old Thurman (28-0, 22 KOs, 1 NC), of Clearwater, Florida, is heavily favored to beat the 34-year-old Lopez (36-7, 19 KOs, 1 NC), of Riverside, California, in the main event of FOX’s three-bout broadcast.

Thurman will fight for the first time since defeating Danny Garcia (34-2, 20 KOs) by split decision in their 12-round welterweight title unification fight 22-plus months ago at Barclays Center. Surgery on his right elbow and a subsequent injury to his left hand were the primary reasons for Thurman’s lengthy layoff.

His hiatus cost Thurman the WBC welterweight title. That championship now belongs to Shawn Porter (29-2-1, 17 KOs), who won it by beating Garcia by unanimous decision September 8 at Barclays Center.

Thurman will defend his WBA “super” world welterweight title versus Lopez.

“I saw a ready fighter, man,” Thurman told FOX’s Heidi Androl following the weigh-in. “We’re gonna have a good fight. You know, he looked game. But his eyes aren’t his hands, baby. You know, he’s gonna get hit tomorrow night – believe that!”

Lopez expressed comparable confidence, though less demonstratively.

“[My confidence is] in the preparation,” Lopez said. “That’s where it comes [from]. I’ve got a great team – Robert Garcia. And I’ve prepared at a championship level and I’m ready to go.”

Before Lopez and Thurman stepped on the NYSAC’s scale, Kownacki came in at 258½ pounds for his 10-round heavyweight fight against Gerald Washington.

The 6-feet-3 Kownacki (18-0, 14 KOs), born in Poland and raised in Brooklyn, was five pounds lighter than when he weighed in for his September 8 fight against Charles Martin. Kownacki, 29, defeated Martin () by unanimous decision in a thoroughly entertaining, 10-round fight at Barclays Center.

The 6-feet-6 Washington (19-2-1, 12 KOs), a former USC football player from Vallejo, California, weighed 243¼ pounds.

Mongolia’s Tugstsogt Nyambayar (10-0, 9 KOs) and the Dominican Republic’s Claudio Marrero (23-2, 17 KOs) also made weight for the third televised fight.

Nyambayar, 26, and Marrero, 29, each weighed 125½ pounds. Marrero and Nyambayar, a 2012 Olympic silver medalist, will fight for the vacant IBO world featherweight crown.

“We have three very significant TV fights that, in my opinion, will also be very fan friendly,” said Anthony Catanzaro, the Barclays Center’s senior boxing adviser.
