Schalke 04 defender Dennis Aogo has been ruled out for the rest of the season after tearing ligaments in his right knee.

The 26-year-old, who has recently been linked with Roma and Liverpool, sustained the injury during training on Friday.

"A medical examination this evening showed a cruciate and interior ligament tear in the right knee," read a statement from the Bundesliga club.

"The left-footer is expected to miss the rest of the season."

Klaas-Jan Huntelaar, Kyriakos Papadopoulos, Jefferson Farfan and Kevin-Prince Boateng are also on the treatment table at the Veltins-Arena.
