These two Eastern Conference teams are neck and neck, jockeying for position in the playoff race.
Houston (10-8-6) and Chicago (10-10-7) are in sixth and seventh place in the Eastern Conference, respectively, both angling for the playoffs. Each with a game in hand over fifth place New England and two in hand over New York, Sporting and Philadelphia, the team that wins this would have its playoff destiny in its own hands.
History doesn't bode well for the Fire, however. The Windy City side has won just one of its last nine meetings with Houston, and all-time, Houston has eight wins to Chicago's four (six draws).
A big part of Chicago's playoff drive has been forward Mike Magee. Since joining from the LA Galaxy, he's scored eight goals in 12 games an contributed three assists to help Chicago overcome a relatively porous back line that has conceded 34 goals.
Houston will be boosted by a midweek win over Arabe Unido in the CONCACAF Champions League. After going down to an early penalty kick, Cam Weaver scored a goal in each half to earn three points.
