Katie Taylor's May 20 rematch with Amanda Serrano is now a major doubt to go ahead due to an injury suffered by the Puerto Rican.
It is understood Serrano has suffered an injury in training and is a major doubt for the scheduled bout in just over two and a half months time, which is scheduled to take place at the 3Arena in Dublin.
If Serrano cannot make the May date, she could face Taylor at Croke Park in an event Matchroom are planning to stage in September.
Among the opponents Taylor could now take on in May are Chantelle Cameron, Natasha Jonas (who she defeated in 2021), Estelle Mossely and Mikaela Mayer, who recently stated she would step in to fight the undisputed lightweight champion if something happened to the Serrano fight.
The American said last month: "I know that her and Serrano have a rematch clause and they should be fighting, but if for some reason it doesn’t happen, I’m here, I’m available, give me a call.
"I fully understand what she’s done for this sport and that she is worthy of having her next fight in her hometown at Croke Park. And maybe a lot of fighters don’t want to open themselves to that position (of fighting away) but you know me, I really don’t care. I’ll be there if I’m called upon."
Undisputed light-welterweight champion Cameron has also called for the chance to fight Taylor in the past.
She said late last year: "I think the fight makes sense now. I'm undisputed at 140, she's undisputed at 135, there's no more excuses. Before I wasn't a world champion... this and that, whereas now I'm a world champion, I was unified world champion, now I'm undisputed. I think I've proved myself that I'm worthy of fighting Katie Taylor.
"She's boxed people that haven't had those credentials and there's been nothing said. It's just the fight has happened whereas with me it's always been 'she's got to do this, she's got to do that, this and that' whereas now what's left? I've done it so now we can fight."
Serrano's reported injury is the latest in a long list of issues around Taylor's homecoming fight.
The Bray native has never fought on Irish soil as a professional and was expected to headline a show at Croke Park on May 20.
But the Jonas Road venue is no longer an option for that date due to costs associated with hiring the venue, which promoter Eddie Hearn claims are "three times more than Wembley".
