Relegation tie-breaker
The 3 last-placed teams in Serie A were guaranteed relegation. However, due to a tie for 17th place between Lucchese and Triestina, the teams had to play a tie-breaker to determine which team would be relegated and which team qualified for the playoff.
Since it was decided to reduce the number of Serie A teams from 20 to 18 for the 1952-1953 season, only the top 16 teams in Serie A were guaranteed to remain there the following season, and only the first-placed team in Serie B was guaranteed a direct promotion to Serie A. The 18th team would be decided in a one-game playoff between the 17th-placed team in Serie A and the 2nd-placed team in Serie B.
