Fight card and bout
The fight card includes every scheduled contest at an event. A single fight is a bout or matchup. Order and broadcast segments can change until event day because of injury, missed weight or regulatory decisions.
Early prelims and prelims
Early prelims are an initial undercard block most familiar from large UFC events. Prelims form the standard undercard. The label does not automatically define sporting quality: recognizable names and important ranking bouts can appear there.
Main card
The main card is the central broadcast block and normally contains the most prominent or commercially important bouts. When several broadcasters are involved, the main card can also mark a platform change.
Main event and co-main event
The main event is the final and officially featured fight. The co-main event immediately precedes it. A main event does not have to be for a title, and on unusually strong cards a championship bout can appear earlier.
Title fight, eliminator and catchweight
A title fight contests a regular or interim championship. An eliminator is intended to identify a future challenger, although its formal status differs between promotions. Catchweight describes a specifically agreed limit outside a standard division.
Why start times move
Published times may refer to the first bout, the main card or a television broadcast. A specific fight time is normally an estimate because early finishes and long decisions move the running order. CS.C therefore labels only reliably confirmed event start times.
