The striker fractured his foot in a training session with the Italian under-21 side last week.
London: Liverpool's Italian striker Fabio Borini will not play again this year after undergoing surgery on a fractured bone in his foot, the Premier League side said in a statement on Wednesday.
Borini, who signed from Roma in July but has yet to score in the league, sustained a foot injury in the league clash with Manchester United last month.
He then aggravated the problem, resulting in a fracture, while training with the Italian under-21 side last week.
"Typically, an injury of this nature requires a three-month rehabilitation period," Liverpool said in a statement on their website (www.liverpoolfc.com).
His absence means Liverpool have just the one recognised striker - Uruguayan Luis Suarez - until the January transfer window.
The Anfield club, who let England striker Andy Carroll go out on loan to West Ham United, have endured one of their worst starts to a top flight season, winning just one of their opening seven league matches.
