The relegation play-offs, originally scheduled to be held between Salernitana and Sampdoria on the dates of 19 and 26 May 2025, was successively postponed after Brescia was reported for financial irregularities that might lead to the club being deducted four points as a result. On 26 May, Lega B decided that the relegation play-offs would probably occur between 15 and 20 June 2025. On 29 May, Brescia's four-point deduction for administrative violations was confirmed, however, Lombard club appealed the judicial verdict with the decision coming on June 12. On that day, their appeal failed after they dropped the appeal. On 17 June, Lega B announced that the relegation play-off second leg would take place on 22 June 2025.
