On-loan Inter defender Lorenzo Pirola has suffered a sprain to his knee which will keep him out of action for his current club Monza.

This according to the Serie B side’s official site, where they confirm that the 19-year-old picked up the injury while on international duty with the Italian Under-21 team, though it is not yet known how long he will be on the sidelines.

Pirola was playing for the Azzurri Under-21 team against Ireland’s Under-21 team when he picked up the injury which forced him to come off the pitch.

The young defender was later assessed for the problem, with the tests revealing that he has picked up a knee sprain.

Pirola has been at Monza this season on loan with the Serie B team having decided to renew his loan after he impressed last season, but so far he has struggled for regular playing time with injuries in particular having been an issue.
