Toronto FC visit Bridgeview, Illinois to take on the Chicago Fire. The Reds are first in the Eastern Conference - and MLS - and could pull nine points clear of the Fire, currently third, by winning.
On the other hand, a Chicago win brings them to within three, so it’s a true six-pointer in the Supporters’ Shield race.
Kick-off: 8 p.m. ET
Venue: Toyota Park, Bridgeview
Chicago have a lot of injury problems in defence and Johan Kappelhof may be the only normal starter they have available for this game.
