Toronto FC says manager Ryan Nelsen and assistant coach Fran O'Leary are not appealing their suspensions following ejections in last weekend's loss to Sporting Kansas City.
The decision means both men will have to sit out Saturday's home game against D.C. United.
Assistant coach Jim Brennan will lead the Major League Soccer team in their absence.
The game features the two worst clubs in the East. D.C. United is 3-20-6 while Toronto is 4-15-11.
D.C. United is likely to rest some key players since it plays Real Salt Lake on Tuesday in the final of the U.S. Open Cup.
