It'll be Haney's first fight under his new exclusive multi-fight deal with DAZN.

Haney is a San Francisco native, and this isn't his first time headlining at the home of the Golden State Warriors. He beat Regis Prograis there by unanimous decision in December 2023 to win the WBC junior welterweight title.

Paro was on that card, too. He knocked down Montana Love twice and stopped him in the sixth round in the co-feature. The fight will be co-promoted by Devin Haney Promotions and Top Rank.

Haney (33-0, 15 KOs), The Ring's No. 1 welterweight and No. 8 pound-for-pound fighter, hasn't fought since he dropped and outpointed Brian Norman Jr. last November in Riyadh, Saudi Arabia. It was Haney's first fight at the 147-pound limit and answered plenty of questions.

Ryan Garcia knocked Haney down three times in their April 2024 fight. Haney lost by majority decision, and the result was changed to a no contest after Garcia tested positive for ostarine.

Haney, who turns 28 next month, is a former undisputed lightweight champion. He beat George Kambosos Jr. twice in 2022 and Vasiliy Lomachenko in 2023.

The Paro bout comes together after Haney's talks with Ring and WBO 140-pound champion Shakur Stevenson fell apart. Weight and a rehydration clause were among the sticking points. Before that, the WBO ordered a purse bid for a mandatory defense against Keyshawn Davis, but Davis withdrew after rejecting the terms.

Paro (28-1, 16 KOs), a 30-year-old southpaw from Australia, won the IBF title on June 24 with a unanimous decision over Lewis Crocker in Brisbane. All three judges scored it 115-113. With that win, he joined Jeff Fenech as the only Australian-born fighters to win titles in two divisions. Dec. 19 will similarly be his first title defense.

The winner will hold two of the four welterweight titles. Garcia holds the WBC belt and Teofimo Lopez holds the WBA title, and they're working toward a unification bout targeted for Feb. 6.
