Gareth Batty will miss the Friends Life t20 finals day after being banned for two matches for his "appalling" conduct in Surrey's quarter-final win over Somerset.
Batty was penalised for two level two breaches by an ECB Cricket Discipline Commission on Friday, triggering an automatic suspension.
The 35-year-old will therefore miss Surrey's semi-final clash with Hampshire and the final, should Surrey reach the competition's climax on August 17.
Batty clashed with Somerset's Peter Trego during Tuesday's quarter-final in an incident labelled as "appalling" by the England and Wales Cricket Board.
Somerset's Craig Kieswetter was also reported by umpires Tim Robinson, Michael Gough and Steve O'Shaughnessy but escaped a ban after a level one offence.
He received a reprimand and three penalty points - short of the nine penalty pionts which triggers an automatic ban.
Gerard Elias QC said: "This was a high profile televised match with much at stake for both sides. In these circumstances, the Cricket Discipline Commission expects players to have regard to the image of the game and their place as role models, and to control their emotions accordingly.
"Gareth Batty was not merely a player but was the Surrey captain. His conduct as such was appalling. Not only was he involved in deliberately and inappropriately physically confronting a batsman he had just dismissed, he subsequently engaged in a foul mouthed tirade at the batsman.
"Plainly, he acted contrary to the spirit of the game and in a way which brings cricket into disrepute and failed to set the leadership example expected."
