The Hampshire County Cricket Club on Monday fined English cricketer Dimitri Mascarenhas £1,000 for his comments about England's national selector Geoffrey Miller on Twitter.
The right-handed batsman and medium-fast bowler could face disciplinary action for using abusive words against Miller on the microblogging site.
His first tweet said: "Chairman of selectors came and didn't even come and say hi.. What a p***k.. Doesn't take much to say hello does it."
Mascarenhas was referring to Miller's appearance at the county match between Lancashire and Hampshire at Liverpool last week.
In another message, the batsman said "Geoff Miller is a complete knob. He had no clue what he is doing. Fing p***k."
The England & Wales Cricket Board began investigating the comments on Monday.
Hampshire County chairman Rod Bransgrove warned the county players about the dangers of conducting personal or private dialogue on social media.
Last week, Mascarenhas' former teammate Kevin Pietersen was also fined over a similar outburst on the social networking site.
