Kieron Dyer's latest comeback has taken a step backwards and his rehabilitation programme has been hit for six. Not only will he miss the Arsenal match this weekend, but is also unlikely to be risked in Newcastle's next Premiership match against West Ham United on December 17.
It is unclear what he is suffering from because recent tests showed nothing that could threaten his career.
Whatever it is, is causing Graeme Souness immense frustration as he looks at the walking wounded and the manager must wonder if his top players really want to play for him.
Michael Owen and Steven Taylor looked certain to return this weekend, but now there is a danger that both could again miss out.
Owen, who is hoping to come back from a groin strain, still has a chance of making the side, but Taylor is unlikely to return until the trip to Anfield on Boxing Day.
