A prospect is a promising fighter, often young, who is rising through the ranks with the intention of one day being a contender for a title. When they reach the higher levels and have an impressive win to loss ratio, they are often referred to as a top prospect. At this time they may have shown promise and skill, but not yet been tested against tough opponents.
To reach the next level and be in contention for belts, the top prospects often face gatekeepers who give the prospect a chance to show the true level of skill and heart, as well as adding to their prestige and popularity if they win, which are important factors in increasing their earnings.
