The Rossoneri have revealed the Brazilian defender will not be available for the crucial European clashes after limping out of the win over Roma on Saturday evening
AC Milan have announced that Thiago Silva will miss both Champions League legs against Barcelona after suffering a a muscular problem.
The 27-year-old limped off in the first half of Milan's 2-1 victory against Roma on Saturday, with coach Massimiliano Allegri confirming in the post-match press conference that the defender was automatically ruled out of Wednesday's Champions League quarter-final first-leg with Barcelona.
Further assessment of the injury has shown that Thiago Silva has suffered an injury to the biceps femoris of the right thigh, with an estimated recovery time of three to four weeks.
This means that the Brazilian will at least sit out of Milan's next six matches, including the Champions League double-header tie against the holders.
Thiago Silva, who joined Milan in 2009 in a €10 million deal, has made 36 appearances in all competitions in 2011-12, scoring three goals.
