Barcelona have confirmed that they will appeal the yellow cards shown to Gerard Pique and Luis Suarez in Saturday's 3-0 win at Leganes.
Pique was booked in the first half for a pull on Nordin Amrabat, with Barca boss Ernesto Valverde describing the caution as "excessive".
Unless the appeal is successful, the defender will miss next Sunday's La Liga trip to second-placed Valencia.
Suarez, meanwhile, was booked for impeding Leganes goalkeeper Ivan Cuellar from clearing the ball early in the second half.
"FC Barcelona informs that it has decided to appeal to the competition committee for the yellow cards shown to Gerard Pique and Luis Suarez during the course of Leganes-FC Barcelona," Barca said in a statement.
With Javier Mascherano out for a month due to a hamstring injury, Valverde may be forced to hand Thomas Vermaelen his first La Liga appearance of the season at the Mestalla.
