A CUT

SOURCE: BBC Sport

A frequent cause of postponements and cancellations, fighters and trainers dread the possibility of sustaining a bad cut in preparation for a big fight.
Head guards are designed to prevent this manner of injury but, while they greatly reduce the likelihood of a fighter sustaining cut eyes, they are not infallible.
While some fighters are accused of being disingenuous when they withdraw from a certain date, it seems extremely unlikely that any boxer would fake a cut, although David Haye was suspected of precisely that when pulling out of a scheduled blockbuster with Tyson Fury in late 2013.
