The suspension comes after Maresca received a second yellow card and was subsequently sent off during a recent match against Liverpool.
The incident occurred when Maresca left his technical area to celebrate a late goal with the players and fans, which resulted in him being booked for the second time.
Maresca had already received a yellow card earlier in the game for protesting a penalty decision.
As a result, he will not be in the away dugout when Chelsea face Forest after the international break.
