The Football Association have rejected Stoke City's appeal against the red card shown to Jonathan Walters at Norwich City on Saturday.
The Republic of Ireland forward, who will now serve a three-match ban, was given his marching orders by referee Andre Marriner following a high challenge on Alex Tettey soon after equalising from the penalty spot in the second half of the 1-1 Premier League draw at Carrow Road.
Stoke manager Mark Hughes described the decision as "harsh" and the club launched an appeal, but the FA believe Marriner was right to brandish a straight red.
A statement on the FA's official website said on Tuesday: "Following an Independent Regulatory Commission hearing today, a claim of wrongful dismissal concerning Stoke City's Jonathan Walters was rejected.
"Walters was dismissed for serious foul play during the game against Norwich City on 8 March 2014.
"His three-match suspension will commence with immediate effect."
The former Ipswich Town man will miss the top-flight clashes with West Ham, Aston Villa and Hull City,
Walters joins team-mate Charlie Adam on the sidelines after he was dismissed in the victory against Arsenal earlier this month.
Adam received a three-match ban after he appeared to stamp on the leg of Arsenal's Olivier Giroud.
Stoke's appeal against that decision was also rejected, which prompted the club's chief executive Tony Scholes to hit back at the FA, as he said: "I am not surprised because clubs like ours very rarely succeed in appeals to the FA."
The Staffordshire club have now expressed their disappointment at losing Walters for three games.
A statement on the club's official website said: "The club gave careful consideration to whether or not to appeal Jon's sending-off but we felt compelled to do so in the interest of consistency after three incidents of a more serious nature in the Premier League last weekend failed to result in red cards.
"We are disappointed with the lack of consistency that this decision seemingly supports."
