Leeds United manager Simon Grayson has banned his players from using Twitter.
It comes after striker Davide Somma posted details about his knee injury on his Twitter account.
The South African international broke the club's rules on social networking by revealing that he would be out for five or six months.
Grayson told the club's website: "There are certain things within football clubs that shouldn't be discussed in a manner like this."
He added: "In the case of Dave's injury, I wanted it to come out in the right manner when everything was 100 per cent confirmed and all the right people knew.
"The guidelines are there for the lads to follow, but if they can't be followed then I'm simply not having it. I have told them I don't want them using it."
It was not Leeds' first brush with the Twitter controversy. In the wake of his transfer to Leicester City, keeper Kasper Schmeichel used the social networking site to deny the club's claims that he had requested a move.
Indeed, Twitter has got a few sports people into hot water.
Liverpool midfielder Ryan Babel was fined £10,000 by the FA after criticising referee Howard Webb's performance against Manchester United in January 2010.
The Dutchman also posted a link to a mocked-up picture of the South Yorkshire official wearing a Manchester United shirt.
Kevin Pietersen was handed an undisclosed fine by the ECB after his outburst on Twitter following his omission from the England one-day and Twenty20 squad to face Pakistan in September last year.
And recently that he was "glad to be out of there" after he was told he could leave Portman Road in the summer on a free transfer.
In a statement in February, the Football Association warned players about the use of Twitter and other social networking sites.
It read: "Comments made on social network sites may be considered public comment, any comments that are deemed improper, bring the game into disrepute, or are threatening, abusive, indecent or insulting may lead to disciplinary action.
"Participants are required to act in the best interests of the game at all times and should be aware of this when using social networking websites.
"In addition, we would remind participants that social networking postings could also lead to civil proceedings being brought by affected parties."
