Pacos de Ferreira climbed to third on the Liga Sagres table after beating Estoril 1-0 in their postponed match on Tuesday.
The match, locked at 0-0, was halted in the 76th minute on Monday after heavy fog engulfed the Estadio da Mata Real in Porto.
The teams agreed to return the following day, with Manuel Jose handing Pacos de Ferreira the lead three minutes after the resumption.
Pacos de Ferreira move 14 points behind leaders Porto and Benfica, while Estoril remain in eighth place, five points above the relegation zone.
Estoril entertain sixth-placed Vitoria Guimaraes on Friday, while Pacos de Ferreira travel to fourth-placed Sporting Braga on Monday.
