Newcastle midfielder Kieron Dyer will be out of action for at least two weeks after a freak training ground accident.
Dyer has been plagued by injury during his time at St James' Park
The 27-year-old, who returned to action against Portsmouth in the Carling Cup on Wednesday after six months on the sidelines, damaged his left eye.
"Kieron took a knock to his left eye in Friday training in what can only be described as a freak accident," manager Glenn Roeder told the club website.
"He will not take part in contact training for at least two weeks."
Roeder added: "Kieron does not deserve such wretched luck to happen little more than a day after getting back out on the pitch against Portsmouth.
"For 30 minutes he showed the kind of electric pace and ability that we know he is capable of.
"It is such cruel luck to be robbed of his services, but we have just got to stand up and be counted and move forward in a positive way, starting with Charlton on Saturday."
Dyer was set to make his first start since April against the Addicks.
