Earlier this week, David Haye revealed that he suffered a torn bicep and it forced him to postpone his heavyweight rematch with Tony Bellew.
The British pair were slated to do battle for a second time on December 17 at London's O2 Arena.
Bellew, who dropped his WBC cruiserweight title and moved up to the heavyweight division, pulled off a shocking eleventh round TKO of Haye at the same venue in March, aided by the former heavyweight world champion suffering a serious ankle injury mid-bout.
Haye suggested that the pair will attempt to reschedule the fight for March 24 or May 5 in 2018.
There is a possibility that Bellew will take an interim-fight - depending on how long it takes Haye to fully recover.
On Wednesday the 37-year-old former two division world champion posted a video on social media, where he sent a message to fans regarding the injury, his comeback and assured everyone that he plans to be back even stronger than ever.
"I am sure you are already aware that my much-anticipated rematch with Tony Bellew has been postponed," said Haye.
"I have obviously got an injury in my left bicep and I had a procedure to repair it a couple of days ago. Doctors, my physio are very, very happy with how it went.
"I will be back firing on all cylinders in a couple of months. Sorry to everybody. This sport throws curveballs at us from time to time but I will be back
"Thanks for the amazing support people have been sending my way, it really means a lot that you guys have got my back.
"It has been a very challenging year for me but 2018 is when it is all going to happen. Have a great Christmas. I am going to be working through my Christmas and I will see you next year."
