Kieren Fox and Richard Hughes were the first jockeys to fall foul of new whip guidelines set out by the British Horseracing Authority, which came into effect yesterday.
Fox, who claims 3lb, was handed a 15-day ban at Salisbury after hitting Orthodox Lad 11 times -- seven times in the final furlong -- when winning the Bathwick Tyres Salisbury Handicap by a short head.
Hughes was given five days after finishing third on Swift Blade, who was adjudged to have been hit six times inside the final furlong during the same race.
The revised sanctions state a Flat jockey can only hit their mount seven times, and just five times inside the final furlong.
Both jockeys will lose their percentage of prize-money and will also have to forfeit their riding fee.
Hughes said: "I'll have to go back to school to learn how to count. I knew exactly what I was doing and I was aware -- I hit him down the neck for correction matters, nothing else.
"They said you aren't allowed to use your stick as correction and I was under the impression you were allowed to do that."
Jockeys in action at Yarmouth and Windsor on the same afternoon escaped any punishment under the new guidelines.
