The SFA has thrown out an appeal from Kilmarnock over Gary Dicker’s sending off in last weekend’s 1-0 loss to Hearts at Rugby Park.
The Irishman was shown a straight red card by referee Willie Collum for a challenge on Jambos midfielder Calumn Morrison.
Killie vowed to appeal the decision but a judicial panel upheld the charge of “serious foul play” at a fast-track tribunal on Wednesday.
The 32-year-old will miss the away trips to take on Aberdeen, and Hibs.
Rugby Park boss Steve Clarke said in the aftermath that he was “sure” the midfielder would have the red card rescinded, adding: “I’m disappointed with an experienced match official who couldn’t wait to get the card out his pocket before he’d assessed and thought about the situation.”
Dicker himself tweeted after the match: “Games gone if that’s a red card! Gutted for the boys after going down to 10 men and working so hard.”
