Striker Craig Bellamy has been told he has no future at Newcastle United.
Bellamy, currently on loan at Celtic, allegedly sent insulting text messages to Magpies captain Alan Shearer after the FA Cup defeat by Manchester United.
Newcastle chairman Freddy Shepherd confirmed that messages were received and told the Daily Express: "He got more than he bargained for from Alan.
"He was so riled he reacted. He told Bellamy he would knock his block off if he ever set foot back in Newcastle."
Shepherd also confirmed that Bellamy texted his son Kenneth as well as his former Tyneside strike partner.
He added: "The text he sent to Kenneth was mildly upsetting but what he said to Shearer was insulting.
"It was along the lines that he was past it and his legs had gone - and that he was going to come back here from Celtic.
"I can tell you there is no chance of that. Bellamy has taken on a hero in Alan and there is only one winner of that one. And it is not Bellamy.
"He has since claimed that he lost his phone. I suppose it was found by someone who knew Alan and Kenneth's numbers."
In February, Bellamy completed a loan move to Celtic until the end of the season after a public fall-out with Magpies boss Graeme Souness.
The Welsh striker will miss the rest of Celtic's campaign because of a hamstring injury and his long-term future has yet to be resolved.
