Betting for the Liga match was suspended after large bets were being placed on the match. Reports in the Portuguese press alleged that one bet alone from abroad, reportedly China, amounted to 100,000 euros.
This is the first occasion betting has been called off for a top flight Portuguese football fixture.
The game ended in a 2-1 victory for Feirense, with both managers afterwards praising their players for giving their all and delivering a top class game in which they say players were clearly beyond suspicion of any involvement in the odd nature of the pre-match betting.
