FC Porto failed to make the most of an opportunity to narrow the gap to the Liga leaders as they were held 1-1 by Pacos Ferreira.
With Braga and Benfica not playing until tomorrow Porto could have put the pressure on with a win, but they fell behind seven minutes from time through Araujo Maykon.
Falcao levelled two minutes later though, before Maciel Ozeia saw red for the visitors a minute from time.
Sporting Lisbon fell a goal behind through Ruben Micael's 24th-minute strike but came back to beat Nacional 3-2.
Miguel Veloso levelled just a minute later before Liedson's double (59 and 71) put them in control, despite Edgar's late strike for the visitors.
Elsewhere, Guimaraes and Vitoria Setubal drew 2-2, while Olhanense claimed just their second win of the season, 1-0 over Naval.
