Montoyo also said pitcher Chase Anderson, who is dealing with an oblique injury, will throw a simulated game soon. Meanwhile, outfielder Randal Grichuk is considered day-to-day after leaving Sunday's game with back irritation.
Third baseman Travis Shaw is attending a family matter and is not with the team in Washington.
Toronto was set to face the Nationals on Monday night.
Just before first pitch, leadoff hitter and shortstop Bo Bichette was scratched because of left hamstring tightness.
