Toronto FC will be without their bench boss Saturday evening against the New York Red Bulls.
Robin Fraser will serve a one-game suspension for yellow card accumulation, according to the official MLS disciplinary report.
TFC was already going into the match without defenders Richie Laryea and Benjamin Kuscevic, who are both out due to yellow-card accumulation.
Toronto faces a critical game if it hopes to stay in the playoff hunt. TFC currently sits 11th in the East, two spots and four points adrift of FC Cincinnati, which holds down the ninth and final playoff berth.
Both Cincinnati and 12th-place D.C. United have a game in hand on Toronto, which has five matches remaining.
