Sevilla defender Antonio Luna will miss two matches after being sent off against Atletico Madrid last weekend.
The 21-year-old was on the bench for the game with Diego Simeone's side, but was heard shouting offensive gestures from the bench.
The full-back was given a red card by referee Ignacio Villanueva in the 76th minute, and the Spanish Football Federation (RFEF) have retrospectively decided on a two-game suspension.
Teammate Federico Fazio was also given his marching orders in the first half for a foul on Koke, and will miss just the one match.
