Villarreal striker Giuseppe Rossi has been ruled out of action for the next ten months.
It was originally thought that the 25-year-old would miss around six months after he tore his anterior cruciate ligament for a second time on April 13.
However, it has now been revealed that the Italian international requires another operation, which has added four months to his recovery time.
"With the objective that Giuseppe Rossi returns to his best physical condition, the most secure procedure consists of two separate operations," a statement on the club's official website read.
Rossi joined Villarreal from Manchester United in 2007.
