The ban means Maresca will not be on the touchline for Chelsea's match against Everton this weekend at Stamford Bridge.
The reason for the ban is due to a yellow card he received during Chelsea's recent match against Fulham.
Maresca was involved in celebrations after a late goal was scored, which led to the yellow card.
Chelsea's assistant manager Willy Caballero is likely to take over Maresca's responsibilities for the Everton match.
Maresca is expected to return to his role for Chelsea's match against Liverpool in two weeks' time.
