Somerset bowler Jamie Overton has been penalised by the England and Wales Cricket Board for a breach of code.
The incident occurred during the final County Championship match of the season against Nottinghamshire.
The umpires took the 19-year-old England Lions paceman out of the attack for excessive short-pitched bowling, having already given him a warning.
He has been given a reprimand for a level one breach, which will remain on his record for two years.
Overton took two wickets in the Division One match at Trent Bridge last week, which ended in a draw.
