British heavyweight Dereck Chisora believes that David Haye's "passion" for the sport will ensure that he returns to the ring after shoulder surgery.
Haye has been advised to retire by doctors after undergoing a five-hour operation two weeks ago that ruled him out of a domestic encounter with Tyson Fury, but Chisora has insisted that he doesn't expect the two-weight world champion to hang up his gloves.
The 29-year-old told reporters: "He will be back. David Haye will be back because he likes boxing. It is difficult to get away from it if you have the passion."
Haye defeated Chisora inside five rounds in July 2012.
