Ghana striker, Matthew Amoah has suffered another injury setback with his club, Borrusia Dortmund.

The striker who missed a greater part of the German Bundesliga last season through a knee injury picked up the same injury last Friday at training.

Amoah, now faces a possible knee surgery.

The 25 year-old Black Stars player only made his Dortmund debut last season on match-day-27 after a long lay off due to injury.

He was expected to begin this season with a bang after playing through all of Ghana's four game at the World Cup and the Black Stars' 2-0 win in their last international friendly against Togo on August 15.

But after consultation with Dortmund team physician, Dr. Markus Braun, Amoah, who joined the team during last season´s winter break from Vitesse Arnheim, has travelled to see a trusted physician in Holland to have a look at the damaged meniscus.

"After that, a decision on whether he will have arthoscopic surgery will be made," said Dortmund coach, Zorc.

If the suspicion of a meniscus tear is confirmed by this examination, the duration of Amoah's absence remains unknown.
