The Paris Saint-Germain coach is unwilling to take risks with the Brazilian's fitness ahead of the central defender's return to first-team action following a thigh injuryParis Saint-Germain boss Laurent Blanc says that the club must be "very careful" in easing Thiago Silva back into the frey as he returns to training following a six-week lay-off.
The Brazil international has been sidelined with a thigh injury since the 1-1 draw with Ligue 1 rivals Monaco in September.
Despite returning to full training, the 29-year-old is not expected to resume first-team duties for the visit of Lorient to Parc de Princes on Friday, as Blanc believes that the defender's situation must be treated with the utmost delicacy.
The coach told reporters: "This is not a trivial injury. With him, we must be very careful. I am very happy for him because six weeks is a long time.
"This is someone who trains very well and has a healthy lifestyle."
The former AC Milan stalwart could make his long-awaited return for the Champions League clash with Anderlecht on November 5.
PSG, who won Ligue 1 for the first time in 19 years last season, currently sit level on points with Monaco at the summit of France's top flight with 25 points apiece, with Blanc's men ahead marginally on goal difference.
