Leeds boss Simon Grayson has banned his players from using the social networking site Twitter.
The ban is in response to South African striker Davide Somma, who revealed to his followers on Friday that he had torn his cruciate ligament and would be out for six months.
"We have a club policy that players are banned from leaking any information," Grayson told the Yorkshire Post. "It shouldn't have come out like that. It should have been left to me to deal with, hence why from now on all players will be banned from using that sort of network."
He added: "It has caused too many problems for other clubs and other players and we had strict rules about Twitter, which were put in place halfway through last season.
"There were certain people at the club who didn't know (about Somma's injury) and they should have been told before the people on that website.
"There will be major implications for any player caught using it."
