[22] Although it was expected that the three vacancies were to be filled by Catania, Novara and Siena, however Pro Vercelli and Ternana disagreed,[23] and on 10 August, the Lega B announced the 2018–19 season would go ahead with 19 teams instead of the regular 22.
[25] * Starting from this season, the two new unique institutional sponsors for all the teams participating in the Serie B tournament (except for Brescia) are Unibet (on the back under the numbering) and Facile Ristrutturare (on the left sleeve as a patch).
[55] However, on 23 May 2019, the Regional Administrative Tribunal (TAR) of Lazio declared void the procedure followed by the Lega B, provisionally reintroducing the play-out, this time between Salernitana (15th) and Foggia (16th), in accordance with the new standings after Palermo were subsequently placed at the bottom of the league table due to financial irregularities.
Finally, on 29 May, the Court of Appeal of the Italian Football Federation (Corte d'Appello della FIGC) annulled the relegation of Palermo, who were sanctioned with 20 points of penalization instead, and hence changed the composition of the matches, causing the immediate relegation of Foggia, and the re-admission to the play-out of Venezia.
Nevertheless, the players of both teams threatened to boycott the challenge, regarding it as late in the calendar (25 days after the last match), problematic for holidays and recesses of players, and conflicting with the FIFA International Calendar and a resolution of Lega B, according to which Serie B matches could not be held during the national team period (3–11 June).
If tied on aggregate, extra time and a penalty shoot-out would be played because both teams ended up with the same number of points in the table.
According to the new regulations enacted by the FIGC in January 2019, the relegation play-out was consequently considered null and void, and both Venezia and Salernitana were allowed to remain in Serie B.
