Milan striker Pato out for six weeks

AC Milan says striker Alexandre Pato is expected to be sidelined for six weeks after injuring his left hamstring in the midweek win over Palermo.

The Brazilian is the second Milan striker to be ruled out of action in two days after Filippo Inzaghi was diagnosed as needing an operation to repair torn knee ligaments.

It means that Zlatan Ibrahimovic, Ronaldinho and Robinho are the only senior strikers available to Milan coach Massimo Allegri for the city derby against European and Italian champion Inter Milan on Sunday.

So far this season the 19-year-old Pato has scored six league goals to help Milan to the top of the Serie A.
