Reports indicate that Pacquiao, a 12-time world champion across eight different weights, may also have settled on facing an opponent in early 2027 instead, with an official announcement expected soon.
While Cordina had agreed terms to face Pacquiao, the Filipino legend – who has not fought since July 2025 – has not reciprocated.
Hearn previously admitted that he was unsure whether the final details could be agreed.
But the promoter has been adamant in his belief that a Welsh fighter must feature on what is one of the most highly anticipated boxing cards in recent years.
“Not having a two-time world champion from Wales on the undercard is crazy,” Hearn told IFL TV.
Abdullah Mason, Shakur Stevenson and Keyshawn Davis are all fighters that Hearn has name-checked as potential opponents for Cordina if the Pacquiao showdown could not be finalised.
Turki Alalshikh, the co-founder of Zuffa Boxing and a member of the Saudi Royal Court, has confirmed that the 11 December card is not yet finalised.
