Sunderland have confirmed they will not appeal the Football Association charge of violent conduct against defender Phil Bardsley.
The Scotland international will as a consequence begin a four-match suspension which comes into effect from Sunday's match against Stoke at the Stadium of Light.
Bardsley's punishment stands at four games because he has already been sent off this season after seeing red in Sunderland's derby defeat to Newcastle.
The charge comes after the FA reviewed video evidence of Bardsley's stamp on Juan Mata in the loss to Chelsea last weekend, which referee Lee Probert failed to act upon at the time.
His club have no complaints and a statement read: "Sunderland has confirmed it will not be appealing the Football Association's charge against Phil Bardsley following the Premier League fixture with Chelsea on Saturday 10th September.
"The FA yesterday (Tuesday) advised that the defender would be cited retrospectively following an incident involving Chelsea's Juan Mata during the first half of the fixture at the Stadium of Light."
Bardsley will miss the Black Cats' Premier League clashes with Stoke, Norwich, West Brom and Arsenal.
