UPDATE 1-Rugby-Italy's Parisse ruled out by serious knee injury

* Parisse has ligament damage, could be out for six months

* Sole takes his place in team to face Samoa (recasts with Parisse injury)

MILAN, Nov 26 (Reuters) - Italy captain Sergio Parisse suffered a serious knee ligament injury on Thursday and could be missing for up to six months, which would rule him out of February's Six Nations.

The number eight was earlier named in the team for Saturday's final November test with Samoa but his place will now be taken by Josh Sole, the Italian federation said in a statement.

"At the moment the possibility of surgery can't be excluded, which would have a recovery time of around 120 to 180 days," Italy doctor Roberto Pozzoni said.

Stade Francais's Parisse, who injured his right knee in training, has been a driving force for Italy and was especially impressive in their first November test when they bravely lost 20-6 to New Zealand in Milan.

Sole has come in as blindside flanker with Alessandro Zanni moving from six to number eight. Hooker Leonardo Ghiraldini becomes captain and Antonio Pavanello takes Sole's place on the bench.

Parisse's injury is a big blow to the Azzurri, who are desperately seeking a victory in Ascoli on Saturday (1400 GMT) having never beaten the Islanders and having failed to win for over a year.
