Balotelli joins Motta on Italy injury list

MILAN - Italy striker Mario Balotelli is a big doubt for Friday's Euro 2012 qualifier at home to Estonia because of a knee injury, the Italian football federation said in a statement on Tuesday.

Midfielder Thiago Motta had already been ruled out of the Modena match with a leg problem.

Italy, who top Group C, also play Ireland in a friendly next Tuesday in Liege.
