Napoli will be without fullback Christian Maggio for a month as the Italian international is set to undergo knee surgery for a meniscus injury.

The 31-year-old was seen by a specialist in Rome on Monday where it was deemed that the fullback will undergo surgery to correct the problem.

The surgery will take place on Wednesday and it is expected that the former Sampdoria man will miss a month of action before returning for Week 8 of the Serie A season, when the Partenopei will take on Roma.

Maggio has scored 22 goals in 192 appearances for the Azzurri since joining the club in 2008.
