Former world champion Carl Frampton believes it could take "months or even years" for boxing to recover from the COVID-19 pandemic.
The Belfast fighter thinks fans will be reluctant to attend shows even after restrictions are lifted.
"It might take a long time to recover. I'm talking months and possibly years away from getting it back to what it once was," "The Jackal" told BBC Radio Five Live.
"In my position most of the money and the purse I received comes from TV, but there are guys fighting on non-televised shows that need bums on seats and need to sell tickets to make a living.
"If people are apprehensive about large gatherings and these guys aren't going to be able to sell their tickets, or if people can't afford to buy them because they've lost their job or for other reasons. I think it's going to change a lot once we come out the other side of this."
Frampton added that he hopes his WBO super-featherweight clash with champion Jamel Herring can take place before the end of the year:
"I just don't know when it's going to happen now. I hope it does happen before the end of the year but I want to be realistic as well. You'll need at least 10 weeks of a proper training camp with your coaching, bringing in sparring partners.
"People are talking about a fight at the end of the summer, I just don't think that's possible."
