Leeds manager Neil Warnock says goalkeeper Paddy Kenny has apologised to Tony Fernandes after sending mocking messages to the QPR chairman.
Kenny has been fined by Leeds and has deleted his Twitter account, on which he had posted derogatory remarks about QPR, the club he left in the summer following the arrival of Rob Green.
The 34-year-old former Republic of Ireland international sent abusive text messages to QPR technical director Mike Rigg and Fernandes mocking the team's 5-0 defeat to Swansea and goalkeeper Green's performance.
Warnock wrote in his Independent newspaper column: "As I'm sure you are aware, my goalkeeper has been in the news in relation to some text messages he exchanged with people at QPR. I have to say I was disappointed that something that began in good humour got out of hand.
"I've spoken to Paddy Kenny and he was full of remorse and couldn't apologise to me quickly enough. I told him there is no problem with having a drink to celebrate a win like last Saturday's over Wolves but he must be aware of his responsibilities to the club and be careful where he is and what he does.
"I've obviously fined him and he has agreed to finish on Twitter with immediate effect. He has also apologised to Tony Fernandes, QPR's chairman.
"I've also spoken to Tony and told him I honestly believe there will not be a repeat. We ended the call on good terms.
"It is disappointing when something which is essentially a private conversation becomes public the way this has but, as I've told players before, they need to be very careful about texting and Tweeting."
