The 38-year-old Chelsea legend scored his third goal in as many games on Saturday as the Impact drew 1-1 with the Philadelphia Union at Stade Saputo.
The former Chelsea striker opened the scoring just three minutes into the match at Stade Saputo when he pounced on a poor clearance and blasted a ferocious shot past Union goalkeeper Andre Blake into the back of the net.
C.J. Sapong levelled things up for the Union in the 24th-minute with his fifth goal of the season, however, before Impact fans were given a scare 20 minutes from the end when Drobga was forced off for Johan Venegas after taking a knock to his leg.
The hosts were still able to hold on for a point without their star man on the field, but head coach Mauro Biello admitted after the match that he did not know how serious the problem was.
“We can only hope he is ok,” Biello told goal.com when asked about Drogba’s injury. “Still, we have a lot of depth and many quality players. We’ll move forward and hope he can play in the next game.”
Drogba joined the Impact on an 18-month deal last summer after ending his second spell with Chelsea and has since scored 16 times in 21 MLS appearances for the club, helping them reach the Eastern Conference semi-finals last season.
The 38-year-old Ivorian missed four of their first five games this term in order to avoid playing on artificial turf, but he now has four goals in seven matches on the campaign, as well as three assists.
Montreal, meanwhile, sit top of the East after their draw with second-placed Philadelphia, having taken 16 points from 11 games with four wins, four draws and three defeats.
