The Brazilian center -back was forced off against the Giallorossi during the first half and is now unlikely to feature against the Blaugrana in Europe midweek
AC Milan defender Thiago Silva is a major doubt for Wednesday's Champions League quarterfinal clash against Barcelona after being substituted in the 10th minute in Saturday's Serie A game versus Roma with a muscle injury.
The Brazilian was a doubt for the fixture against the Giallrossi and was expected to be rested for the game after picking up a knock during last week's 2-2 draw with Juventus in the Coppa Italia, a result which saw Massimiliano Allegri's men crash out 4-3 on aggregate.
However, the former Fluminense defender was put through his own personal warm-up prior to kick-off and deemed fit enough to start versus Roma.
Silva's injury could prove to be a big blow for the reigning Italian champions who are already set to be without a host of players for Wednesday's first-leg encounter against Barca.
