The Football Association are to question officials at Weymouth and Rushden & Diamonds after suspicious betting on the weekend match between the two clubs.
Weymouth lost 9-0 after their senior players refused to turn out for the Blue Square Premier match because of a dispute over pay.
News of the dispute had spread before the game and bookies took 10 times more than usual in bets on the game - all for a Rushden & Diamonds win.
An FA spokesman said: "We are aware of the concerns and we are investigating unusual betting patterns."
The bookies paid out around £1m but Totesport suspended betting on Saturday morning after "smelling a rat".
Totesport spokesman George Primarolo said: "People have got wind of the team news before the bookies have.
"This sort of thing happens in the lower leagues from time to time."Reuse content
