There are typically multiple fights before the main event in a UFC card. For UFC 300, the main card consists of six fights, culminating in the main event. Usually, there are preliminary fights before the main card, but the exact number of fights before the main event depends on the structure of the event and the number of preliminary bouts scheduled. If referring specifically to UFC 300 as a recent notable example, there are 5 fights before the main event on the main card, plus additional preliminary fights that occur before the main card begins. So, the main event is generally the 6th main card fight in such a structured event. Preliminary fights precede these and can number several, making the total fight count before the main event higher depending on the event schedule.
