Britain’s IBF world heavyweight champion Anthony Joshua will not fight former champion Wladimir Klistchko in 2016 but promoter Eddie Hearn expects a fight in the spring.
The pair were close to agreeing a bout for 10 December but Klitschko has picked up a “minor injury” in training.
The WBA had also yet to state whether its vacant title would be on the line.
“While waiting on the WBA and with Klitschko’s injury, it was a non-starter,” said Hearn.
“Let’s get this over the line for March or April.”
Hearn has reiterated that Joshua will compete in Manchester on 10 December but expects an official announcement on a 2017 meeting with Ukrainian Klitschko later this week.
He added: “We will announce that fight for the spring and give it the build-up it deserves – probably take it to a stadium as well. I’m certain it will happen in the spring.
“We are in talks with the Millennium Stadium [now the Principality Stadium] about their dates in March and April – it has a roof and it can be a bit nippy in London in March or April.”
