Maciej Sulecki competed at or just above the super welterweight limit of 154 pounds in each of his last three fights.

The Polish contender had no difficulty whatsoever making weight Friday afternoon because he was afforded six additional pounds for his middleweight match against Daniel Jacobs on Saturday night. Warsaw’s Sulecki stepped on the New York State Athletic Commission’s scale at 159.2 pounds at Barclays Center in Brooklyn, also the site of their 12-round, 160-pound main event.

Brooklyn’s Jacobs officially weighed in at 159.6 pounds.

According to promoter Eddie Hearn, the winner of the Jacobs-Sulecki fight will become the WBA’s mandatory challenger for Gennady Golovkin’s WBA middleweight title. Jacobs badly wants a rematch after giving Golovkin a very tough fight in March 2017, a 12-rounder he lost by unanimous decision at Madison Square Garden.

The 31-year-old Jacobs (33-2, 29 KOs) is consistently listed as at least a 15-1 favorite over the unbeaten but unknown Sulecki (26-0, 10 KOs).

Jacobs-Sulecki will be the main event of an HBO “World Championship Boxing” doubleheader scheduled to start at 10 p.m. ET/PT. In the opening bout, heavyweight contender Jarrell Miller will attempt to continue on his path toward a title shot against veteran Johann Duhaupas.

Brooklyn’s Miller (20-0-1, 18 KOs) weighed in Friday at 304¼ pounds, 21 pounds heavier than he was for his last fight.

The 6-feet-4 Miller officially weighed 283¼ pounds prior to his previous bout, a ninth-round stoppage of Poland’s Mariusz Wach (33-3, 17 KOs) on November 11 at Nassau Veterans Memorial Coliseum in Uniondale, New York. Miller feels he was too light for that fight and expects to perform better against France’s Duhaupas because he is heavier for their match.

In the bout before he faced Wach, Miller weighed in at 298¾ pounds for his technical-knockout victory over Gerald Washington (18-2-1, 12 KOs) on July 29 at Barclays Center.

The 6-feet-5 Duhaupas weighed in at 244.2 pounds Friday.
