Wladimir Klitschko's rescheduled world heavyweight title defence against Tyson Fury is being lined up for November 28.
Ukraine's WBA-WBO-IBF champion Klitschko (64-3, 53 KOs) pulled out of fighting Manchester's unbeaten Fury (24-0, 18 KOs) in Düsseldorf on October 24 last Friday, just two days after attending a press conference to publicise the fight.
The 39-year-old suffered a calf injury in training but confirmation of the new date for the fight - still to be held at the 55,000 stadium in Düsseldorf - is expected next week, according to Fury's manager Mick Hennessy.
Fury has now had four fights in the last two years postponed but Hennessy is expecting a quick rearrangement.
"It will be at the same arena and we are hoping to have it happen late November or early December," Hennessy told ESPN. "Wladimir is being seen by the specialist who treats the German national football team and they are going to work on it over the next few days.
"We have got to match up what dates are good for the TV stations but the stadium is OK.
"It was like déjà vu for Tyson because two fights against David Haye were called off and the Dereck Chisora one was also postponed. He was upset initially, but it will be rescheduled very quickly and it will happen before Christmas.
"If it only gets put back a month, Tyson will just carry on with the training camp. We get on very well with K2 Promotions and both camps are optimistic we will get this fight done by the end of November and hopefully there's an announcement next week."
Fury had been left brimming with confidence after last Wednesday's press conference with Klitschko to promote their fight on the original date of October 24.
Fury, who dressed up as Batman and wrestled with someone dressed as the Joker, was left feeling he had gained a psychological edge over the Ukrainian, who has reigned for nine years.
"When Tyson does press conferences he plays with his opponent and he felt like he saw a weakness in Wladimir," Hennessy told ESPN.
"He was full of confidence and wanted the fight so bad, then there's the shock of the postponement. But it's not a long delay and he's OK with that."
