Motherwell have fully backed Steve Jennings amid an investigation by bookmakers into the red card he received during Tuesday night's defeat by Hearts.
The Association of British Bookmakers acted after some of their members became suspicious about betting activity surrounding the Clydesdale Bank Premier League clash.
It is understood several bets were placed on a red card being handed out during Motherwell's 2-1 loss, including one of £500 from a new account in Liverpool.
