European soccer's ruling body decided that Jestrovic had racially insulted Liverpool midfielder Mohamed Sissoko during a heated argument in the 75th minute of the game.
Jestrovic said he would not appeal against the decision.
"I accept the decision but unfortunately I was on a losing ticket because the referee's report said one thing and I said another," he told Reuters.
"I am not a racist but unfortunately I don't matter and the referee does."
The 29-year-old Serbian will be ruled out of Anderlecht's remaining Group G matches against Chelsea and Real Betis and a further European game, UEFA said on its website.
