Huddersfield Town’s appeal over Philip Billing’s dismissal at MK Dons has failed.
It means the teenage midfielder will serve a three-match Championship ban, starting with the visit of Ipswich Town on Saturday.
The talented Dane will also be ruled out at Derby County on Saturday March 5 and at home to Reading on Tuesday 8.
Billing, 19, was shown a straight red card for a challenge on Jake Forster-Caskey which referee Michael Bull deemed serious foul play.
He had been on the field for less than four minutes after coming on as a half-time substitute, and it was only his ninth appearance at first-team level.
Town head coach David Wagner said he thought the offence warranted a yellow card at worst.
The Football Association’s regulatory committee ruled on the appeal by Town, who were trailing 1-0, but despite being a man down, fought back for a point courtesy of Nahki Wells’ late equaliser.
Billing was the third Town player sent off during Wagner’s reign after Jonathan Hogg in the FA Cup third-round replay at Reading and Tommy Smith in the Championship clash at Brighton and Hove Albion.
Billing’s ban comes with Emyr Huws, who also plays as an anchor midfielder in Wagner’s 4-2-3-1 system, still sidelined by an ankle injury.
It could mean a return to the starting XI for experienced Dean Whitehead.
The former Middlesbrough man has made four appearances from the bench since returning after a knee injury.
Jamie Paterson has also featured alongside regular starter Jonathan Hogg.
Meanwhile Martin Cranie and Kyle Dempsey could also play there.
