Napoli have confirmed that new signing Alex Meret has suffered a fracture of the left ulna during one of his first training sessions at the club, following his recent move from Udinese to I Partenopei.
The injury reportedly occurred following a collision between the goalkeeper and youngster Francesco Mezzoni.
The 21-year-old goalkeeper was unveiled as a Napoli just last week, following his €22m move to the Stadio San Paolo, and has been viewed as the natural successor to Pepe Reina in the Napoli goal following the Spaniard's move to AC Milan the start of the transfer window.
