Sebastian Fundora’s WBC junior middleweight title defense vs. Keith Thurman is expected to land on Manny Pacquiao’s undercard in late January, sources told The Ring.

The second bout of Pacquiao’s comeback is set for Jan. 24 in Las Vegas, the Hall of Fame boxer announced last week, though sources said the fight could shift to Jan. 31.

Pacquiao was held to a draw in July when he challenged WBC welterweight champion Mario Barrios. Rolly Romero is considered the front-runner for Pacquiao’s January assignment.

Fundora and Thurman were to headline their own PBC on Prime Video PPV on Oct. 25 in Las Vegas before Fundora's hand injury during training camp, postponing their fight.

Fundora’s injury, sources said, occurred when he landed a punch that connected with his sparring partner’s elbow on Wednesday. Fundora received good news when discovering his hand isn’t fractured, but he can’t spar for three weeks because of a contusion, sources said, as the hand is inflamed and swollen.

Fundora (23-1-1, 15 KOs) is rated No. 2 at 154 pounds by The Ring. “The Towering Inferno” is coming off a seventh-round TKO victory over Tim Tszyu in their July rematch.

Fundora scored a split decision over Tszyu last year to win the title in an upset. The 27-year-old has dizzying height for a 154-pounder at 6-foot-5½.

Thurman (31-1, 23 KOs) moved up to junior middleweight in March with a third-round KO victory over Brock Jarvis in Australia. The fight was Thurman’s first in more than three years and was meant to set up a title clash with Tszyu later this year in Australia.

Thurman enjoyed a lengthy title run at 147 pounds and his lone professional defeat came against Pacquiao in 2019.
