LONDON (AP) -- Boxing promoter Eddie Hearn says Joseph Parker has been forced to pull out of his heavyweight fight with Dereck Chisora on Oct. 26.
Hearn, who promotes Parker, posted a tweet on Wednesday to say the former world champion from New Zealand has withdrawn ''due to illness'' and that an announcement regarding a replacement would be made this week.
Parker's manager, David Higgins, has previously told the New Zealand Herald newspaper that trainer Kevin Parry had identified a sore on the boxer's thigh during camp and thought it looked like a spider bite.
Hearn didn't disclose the nature of Parker's illness.
Parker and Chisora were scheduled to fight on the undercard to the World Boxing Super Series super-lightweight final between Josh Taylor and Regis Prograis at the O2 Arena in London.
