Bookmakers have reportedly asked the SFA to look into "suspicious betting patterns" during Dundee's 1-0 defeat to Hearts.
Their concerns centre around the volume of bets placed on yellow cards players for Dark Blues players.
Danny Mullen, Leigh Griffiths and Paul McGowan were all booked by match official Willie Collum during their Premiership defeat on Saturday.
And the Daily Mail state several oddsmakers have now raised concerns over bets that were made.
Those fears have been logged with Scottish football's governing body and their Security and Integrity unit, if any insider betting is uncovered, the case will then be escalated to the compliance officer.
It's also understood bookmakers are considering a formal complaint to Police Scotland about the betting patterns.
SFA's task force is headed up by their security and integrity officer Martin Stolarek, whose deals with issues relating to match fixing. His remit also includes educating clubs, footballers, club staff and match officials about gambling awareness.
The Mail contacted Dundee and Hearts for comments, with the Jambos unaware about any potential investigation.
