Artificial turf, a forced adaptation for several top-flight teams in the Cup

The first round of the Copa del Rey features 56 knockout ties involving 112 teams across different categories, including 16 clubs from Spain's top-flight Primera División. Matches are scheduled to be completed across Tuesday.

As part of this opening stage, numerous fixtures pit non-professional lower-tier teams against elite Primera División clubs. This scheduling forces several top-division teams into a difficult, forced adaptation to artificial turf surfaces used by their lower-category opponents.
