Lopes, 31, received a red card in OL's victory against Ajaccio (2-1) after an uncontrolled outing on Mounaïm El-Idrissy, whom he violently hit in the face.
Lopes had been expelled only once before the match against Ajaccio.
The Portuguese international (14 caps) will therefore be absent for the next three days, in Lorient on August 14, against Troyes on August 19 and in Reims on August 28.
