First-choice goalkeeper Andreas Isaksson will miss Sweden's opening FIFA World Cup™ match against Trinidad and Tobago after suffering concussion in a training accident, a Swedish team spokesman said on Thursday.


A shot from midfielder Kim Kallstrom hit Isaksson in the face during training on Wednesday. The impact knocked him over and he was concussed when he banged his head on the ground.


The Rennes keeper will be out of action for between three and five days, the spokesman said, meaning he would miss Saturday's Group B match with debutants Trinidad and Tobago.


No decision has been taken on who will replace Isaksson, who plays his club football for Rennes in France and appeared for Sweden at UEFA EURO 2004.


The other two goalkeepers in the squad are Rami Shaaban and John Alvbage, both of whom have very little international experience. Former Arsenal goalkeeper, Shaaban made his debut for Sweden last month when he came on as a substitute in a friendly against Finland.


Alvbage won his first cap in a 0-0 draw with Jordan in January.
