The Scottish Football Association have confirmed that the Association of British Bookmakers (ABB) are investigating irregular betting activity regarding the red card shown to Motherwell midfielder Steve Jennings in Tuesday night's Clydesdale Bank Premier League defeat by Hearts at Fir Park.
Reports claim irregular betting patterns surrounded the dismissal of Jennings, who, after being booked by referee Stevie O'Reilly in the early stages of the game for a foul on Kevin Kyle, was shown a straight red with seven minutes remaining after O'Reilly turned down a penalty claim.
The statement continued: "At this stage, we are not in possession of the facts regarding the allegations and are waiting for further information from the Scottish Premier League in due course.
"Once we are in possession of all of the facts we will be in a better position to provide more detailed comment on the matter.
"In the meantime, we will be working with our colleagues at the Scottish Premier League to establish the details surrounding this incident."
