Two relegations for each group and a test-matches for the six placed teams against best Third Division clubs.
Veloci Embriaci lost test-match against Pro Gorizia and relegated.
Treviso lost test-match against Monfalconese, which received a wild card as a team of the newly-Italian Julian March, and relegated.
