Rome  - AC Milan midfielder Gennaro Gattuso could be sidelined for the rest of the season due to a knee injury suffered at the weekend in a Serie A game, the club's website reported Tuesday.

Gattuso, 30, is to be examined in Antwerp, Belgium, by the famed orthopaedic surgeon Marc Martens to ascertain a damage to the cruciate ligament in his right knee, which Milan doctors have already diagnosed.

The international twisted his joint early on in a game against Catania, but managed to remain on the pitch until the final whistle. (dpa)
