Carl Frampton's title fight against super-featherweight champion Jamel Herring has been postponed due to a hand injury.
The Northern Irishman was due to attempt to become a three-weight world champion in London on February 27 but the headline fight has now been put off, with no new date chosen.
"It's just a bit of a twinge to my hand, nothing too serious but I have seen a specialist and his advice was to rest it," Frampton said.
"So I asked about the possibility of a postponement to the fight and it was agreed to.
"It gives me a better chance because I will be going into the fight with two good hands after taking advice from the specialist. It's nothing major though and there is no fracture."
The 33-year-old previously underwent hand surgery on both hands after his victory over Tyler McCreary in December 2019.
"I did go into a fight with a hand injury against Tyler McCreary and ended up requiring surgery afterwards on both hands," added Frampton.
"No disrespect to Tyler, but Jamel Herring is a world champion and at a higher level so I need to be at my best. That is what I intend to be.
"I haven't been able to spar or hit the heavy bags for a while. From next week I have been given the go-ahead to start doing that again. I have still been training, doing loads of running, shadow boxing and hitting the paddles as well, which kind of replicates the pads, but I have not hit anything solid for the last two weeks.
"It wouldn't have sat right with me to pull out if people had spent their hard-earned money on tickets and travel, but this is completely different and I just want to give myself the best opportunity to win and that is it."
