Hannover picked up three points at Kaiserslautern yesterday but coach Mirko Slomka's joy was tempered by injuries to Didier Ya Konan and Mohammed Abdellaoue.

The Lower Saxony side broke into the Bundesliga's top three with their fourth victory of the season, but Slomka was preoccupied by the conditions of two key members of his squad after the game.

"Our delight at the three points is dampened by the injuries to Didier and Moa," he said on the club's website.

"Ya Konan looks like he has torn knee ligaments and Abdellaoue had to go to hospital with suspected concussion.

"He will be kept in for observation and will return to Hannover tomorrow."

Kaiserslautern coach Marco Kurz said his side had also paid a heavy price yesterday, but not in the form of injuries.

"We have been taught a lesson again," he said. "The team started courageously, but midway through the first half, we did not stick to our positions any more.

"As a result, we conceded the goal. This is a learning process that we have got to come through."
