Kaiserslautern striker Dorge Kouemaha has been ruled out for up to a month because of a groin injury.

The Bundesliga side said Wednesday on its website that the 28-year-old Cameroon international - who is on loan from FC Brugge - was hurt in training.

Kouemaha has played two league games for Kaiserslautern, which has two points from three games.

The club is already without Slovak striker Adam Nemec, who fractured two vertebrae and his collarbone when he fell out of a cherry tree last June. He underwent an operation on his collarbone.

The 25-year-old Nemec was also concussed in the accident.
