Irish amateur John Barry was given a hefty suspension when in action at Perth.
Riding City Line for County Dublin trainer Karl Thornton in the the Watch All Scottish Racing Live On Racing UK Novices' Handicap Hurdle, Barry was beaten three-quarters of a length into second by Morning Time (4-1).
However, the stewards found he had used his whip above the permitted level and he will be notified of the dates for an 11-day ban.
Winning Scottish trainer Lucinda Russell and her jockey Peter went on to double their tally with Lord Of Drums (7-2) in the Book Your Christmas Party At Perth Racecourse Novices' Handicap Chase.
Gordon Elliott continued where he left off on Wednesday with yet another winner.

Crookstown, who was assisted by the perennial champion jockey Tony McCoy, went off the 2-1 favourite for the Abba Gold Evening On July 30th Maiden Hurdle but had to ride his luck a little.
Stuart Crawford's Now I Win Again had sadly gone wrong before the final circuit, meaning the final flight was bypassed.
McCoy had appeared to be holding Crookstown together for some time before then, and was all-out to get the ex-pointer home half a length clear on his hurdling debut.
