Portsmouth insist Sol Campbell missed Saturday's game with Derby due to injury, and not due to a demand to join Newcastle.
Campbell's absence from the 3-1 win over the rock-bottom Rams sparked rumours about the veteran defender's future at Fratton Park.
There had been suggestions the England international rowed with Pompey chief executive Peter Storrie in the week leading up to the game and that he had stormed out and asked to be allowed to join Newcastle.
But a Pompey spokesman played down the speculation and attributed Campbell's absence at the weekend to a back injury.
"It's quite simple," said the spokesman in The Sun. "Sol had a back problem and he's been having treatment on it all week.
"We hoped he would be fit, but he couldn't make it.
"I spoke to Peter Storrie about it and he laughed and said it was rubbish."
