Josh Taylor’s run as boxing’s undisputed 140-pound champion might’ve come to an end Friday.

TGB Promotions won a WBA purse bid for the right to promote Taylor’s mandated title defense against Alberto Puello. has learned that the winning offer was $200,000, the minimum for WBA purse bids, and would be split 55-45 in Taylor’s favor in the highly unlikely event he decided to defend his WBA belt against the unknown Puello, who is Taylor’s mandatory challenger.

Taylor’s take from that winning bid would be just $110,000, only $20,000 more than Puello would earn.

TGB was the only bidder Friday. Bob Arum’s Top Rank Inc., Taylor’s promoter, did not bid for the right to promote a Taylor-Puello fight.

Taylor (19-0, 13 KOs), like WBC heavyweight champion Tyson Fury, is among the Top Rank boxers who have been advised by Daniel Kinahan. Arum has distanced himself from Kinahan since the United States Department of the Treasury identified Kinahan early last week as an important component to the Kinahan Organized Crime Group, which allegedly is responsible for murders, trafficking heroin throughout Europe and running guns.

His connection to Ireland’s Kinahan notwithstanding, it seems likely that Taylor will relinquish his WBA super lightweight title based on his low earning potential for opposing Puello. He also holds the IBF, WBC and WBO 140-pound championships.

The Scottish southpaw, who beat previously undefeated Jose Ramirez last May 22 to become boxing’s first fully unified 140-pound champ in the four-belt era, has openly discussed moving up to the welterweight limit for his next fight. Making the 140-pound limit isn’t easy for the 5-foot-10 Taylor, who won a controversial 12-round split decision over Jack Catterall in his most recent fight.

England’s Catterall (26-1, 13 KOs) was the mandatory challenger for Taylor’s WBO junior welterweight title when they fought February 26 at The OVO Hydro in Glasgow, Scotland.

If the 31-year-old Taylor vacates his 140-pound title, the WBA likely would order the Dominican Republic’s Puello (20-0, 10 KOs) to face Venezuela’s Ismael Barroso for its vacant championship.

The 39-year-old Barroso (23-3-2, 21 KOs), a Miami-based southpaw who once held the WBA interim lightweight title, is ranked second in the WBA’s 140-pound ratings, one spot beneath the top-ranked Puello. The 27-year-old Puello, who trains in Las Vegas, is affiliated with Al Haymon’s Premier Boxing Champions.
