Two members of the national team, pacer Wahab Riaz and middle-order batsman Asad Shafiq were severely reprimanded by the Pakistan Cricket Board for using a social networking site during the ongoing tour of the West Indies.
A PCB official confirmed that the two players were reprimanded by the team management in the West Indies for using Twitter.
According to details, Riaz and Shafiq violated their central contract terms by posting tweets.
"Wahab (Riaz) had even posted some pictures of the Pakistan team bus on the social networking site which have now been removed," a PCB source said.
Under the new terms of the central contract, the PCB has strictly prohibited players from using social networking sites on tours.
"Since it was their first offence they were reprimanded but if they do it again they will face heavy fines and may be suspension from some matches," the source said.
Riaz and Shafiq have been the leading performers for Pakistan so far in the series.
The PCB has included some strong clauses in the new central contracts that carry heavy fines and bans for players who violate the code that prohibits them from speaking to the media without permission, entering into endorsement contracts without permission, breaking curfew hours on tours, signing up with agents without approval of the board etc.
