"No contest" (NC) occurs when a bout is ended before its scheduled duration, but excludes a knockout or technical knockout ending. Historically, the usual reason for a no-contest was when the referee determined that one or both boxers were not giving their best (not trying) and decided to end the contest, shooing the boxers out of the ring. No-contests also occurred if the police stepped in to stop the fight, a power failure developed, or rain forced an ending. In recent years many United States commissions have made the official result of bouts that end due to an accidental foul or under unusual circumstances "no contest." Many of these bouts had been previously ruled a technical draw. An NC results in neither boxer officially winning or losing.
Note: BoxRec.com Editors may default a bout's result as "NC" if the official result is unknown. This is done primarily for old-time fights only.
