In the context of Pro Kabaddi League (PKL) auction, FBM stands for Final Bid Match. It is a rule that allows teams to match the final bid on a player who was a part of their squad in the previous season. If a team chooses to retain their maximum allotted six Elite Retained Players (ERP), then they can exercise the FBM option once. If they retain five players, then they can use this option twice, and if the number is lower than five, they can use it thrice. The FBM card brings an element of unpredictability to the auction, as a player who is beloved by fans might be on the verge of switching teams, only to be retained at the last moment.
