The Dynamo get one more home game before the break for the Gold Cup group stage, and they desperately need a win.
Houston has won only once in its last eight games and has slipped from first to fifth in the Western Conference.
Montreal has earned at least a point in six of its nine road games.
Here are the lineups for both teams:
Dynamo Starting XI (4-3-3)
Montreal Starting XI (4-2-3-1)
GK: Evan Bush; D: Chris Duvall, Laurent Ciman, Kyle Fisher, Hassoun Camara; M: Marco Donadel, Hernan Bernardello, Michael Salazar, Bierim Dzemali, Dominic Oduro; F: Matteo Mancosu
Notes
• If the Dynamo win it will be their 100th home victory.
