Other teams
Constructorul Brăila (at that time Progresul Brăila) was relegated to the Local Championship (equivalent of Liga IV or Divizia D) at the end of the 1962–63 Divizia B season due to match fixing. After relegation, a new entity, Laminorul Brăila was enrolled in the re-established Divizia C, the new entity also merging with the old one thus becoming its successor. In this way it was possible that after a single season of absence the team would re-appear in the Divizia B, this time under the name of Constructorul Brăila.

Mureșul Târgu Mureș and ASA Târgu Mureș merged, the first one being absorbed by the second one. The new entity was named as ASA Mureșul Târgu Mureș.
