MONTREAL (AP) -- Didier Drogba scored his fifth goal in four starts for Montreal and Andres Romero also scored to help the Impact beat Chicago 2-1 on Wednesday.
The Impact moved four points clear of Orlando City for the final Eastern Conference playoff spot.
David Accam scored for the last-place Fire in its first game since Brian Bliss took over as coach for the fired Frank Yallop, but Chicago still fell to a fourth successive defeat.
Montreal held on despite being reduced to 10 men for a third straight game after Laurent Ciman was shown his second yellow card in the 90th minute. He will be suspended for a home game Saturday against D.C. United, as will Romero, who got a yellow card for taking his shirt off after netting his goal.

Houston's Will Bruin scored on a tap-in in the 67th minute and 10-man Houston beat Sporting Kansas City.
The Dynamo moved within three points out for the Western Conference's final playoff spot.
Sporting KC lost for the fifth time in seven games.
