Barcelona defender Gerard Pique has been banned for four games following his dismissal in the Spanish Super Cup second leg against Athletic Bilbao.
Pique, 28, was red-carded by referee Carlos Velasco Carballo during the second half of the return game, after TV pictures showed him angrily protesting an offside call in the face of a linesman.
The Catalan club confirmed on Wednesday that they will appeal the suspension.
Velasco Carballo's official report said that the Spain international used foul and abusive language when shouting at the assistant.

"In minute 55 the player [3] Pique Bernabeu, Gerard, was sent off for the following reason: shouting at an assistant referee, "I s--- on your f---ing mother," the report said.
Gerard Pique has apologised for his behaviour in the 1-1 draw, which meant the match finished 5-1 in Athleti's favour, but denied personally insulting the assistant referee.
However, the Spanish FA (RFEF) said the "video supports" the referee's report's claim that Pique did swear at the official.
The centre-back's suspension means he is set to miss the Liga matches against Athletic (away), Malaga (home), Atletico Madrid (away) and Levante (home).
Article 94 of the RFEF's disciplinary code stipulates that "insulting, offending or approaching the referee, assistants, fourth official, directors or other sporting authorities in an intimidating manner will be punished with a suspension of four to 12 games."
Pique has also been fined €3,005 and his club €1,400.
