The Football Association has launched an investigation into alleged coin-throwing during Villa’s 2-1 defeat at Stoke City.
An object was allegedly thrown at Stoke keeper Jack Butland during yesterday’s match at the Britannia Stadium.
The authority is also looking into another coin-throwing incident during Birmingham City’s 2-0 defeat at QPR.
Home players celebrating Junior Hoilett's penalty during their 2-0 Sky Bet championship win over Birmingham were apparently targeted from the stand housing visiting supporters.
Rangers launched their own investigation immediately after the game, and the visitors promised stern action against anyone found responsible.
A QPR statement said: "Queen's Park Rangers Football Club is aware of a coin throwing incident that took place during the first half of today's fixture against Birmingham City.
"A coin from the School End stand, in which the visiting supporters were situated, was thrown towards the Rangers players as the Rs celebrated their second goal in our Sky Bet Championship fixture at Loftus Road.
"The club will continue to review video footage and liaise with the Metropolitan and West Midlands police. The club will be making no further comment at this time."
A Birmingham spokesman said: "If anybody is found to have thrown a coin, we will take the strongest possible action. As a club, we utterly condemn that sort of behaviour.
"We will be liaising with the relevant bodies, including West Midlands Police, to investigate such allegations."
The FA was already looking into an incident in which West Brom's Chris Brunt was hit by a coin allegedly thrown by one of his club's own fans during last weekend's 3-1 FA Cup fifth-round defeat at Reading.
Police have made an arrest in connection with that matter.Subscribe to our Newsletter
