The Football Association has rejected West Bromwich Albion's appeal over the sending-off of Hal Robson-Kanu against Burnley.
In Saturday's game at Turf Moor, Robson-Kanu came off the bench to score the winning goal as the Baggies registered a 1-0 victory over the Clarets.
The forward was later sent off for an elbow on full-back Matthew Lowton, although West Brom soon expressed a desire to appeal the decision.
However, that has been rejected by the governing body, with the Welsh international now due to serve a three-match suspension starting with the EFL Cup fixture against Accrington Stanley.
The 28-year-old will also miss Premier League matches with Stoke City and Brighton & Hove Albion respectively.
