Napoli have officially ruled Marek Hamsik out of their crunch Champions League clash with Borussia Dortmund on Tuesday, after he limped out their shock Serie A defeat to Parma last night.

Hamsik caught his studs in the ground just 10 minutes after coming on a substitute at the San Paolo Stadium and was forced off as Dries Mertens took his place in the closing stages.

The Azzurri have released a statement confirming that the Slovakian playmaker did not suffer a fracture or ligament damage, but has sustained significant bruising to his foot and will not be ready for the trip to Dortmund.

Coach Rafael Benitez will now be forced to consider alternatives in an advanced midfield role against the German giants, with both sides desperate for victory to qualify alongside Arsenal from Group B.
