The next day the England manager, Sven-Goran Eriksson said that Dyer was "almost for sure" out of the World Cup as doctors think it could take almost four weeks before he could start practicing again. "If something could happen in one weeks time, a miracle, I might think about it. But almost for sure he will not play" said Eriksson.

     

                                                                  


Dyer had only just recovered from injury a couple of months earlier but had been playing well for Newcastle since his return and was favourite to start for England on the left side of midfield. He is extremely unlucky to have picked up this injury in the last weekend of the Premiership season.

First reserve Danny Murphy and second reserve Trevor Sinclair had already been called up to the squad to replace the injured Kieron Dyer and Steven Gerrard - Steven Gerrard will not now go to the World Cup due to injury

On Wednesday 15 May however, it was revealed that Dyer's knee injury was not as serious as first thought - Dyer appears to have escaped knee ligament damage and should shortly be running again. Eriksson has asked for Dyer to come and join the rest of the squad in Dubai where his fitness will be assessed over the weekend and up to when the squad is submitted to FIFA on Tuesday 21 May.

On 21 May, Kieron Dyer was named in the 23 man squad submitted to FIFA even though he is still injured at present. Dyer's reserve, Trevor Sinclair returned to England the next day but was later called back to the squad when Danny Murphy became injured.

On 25 May, Eriksson said that if Dyer could not convince him by 1 June that he will be fit for the England game against Argentina then he would be replaced (as 1 June is the last day that Eriksson can replace a player due to injury). Eriksson said that if Dyer took a medical examination today he would fail it.

On 31 May, Kieron Dyer said he has now recovered from injury and that he may well be a substitute for the game against Sweden on 2 June.
