He General Regulations of the Spanish Football Federation (edition of the month of September 2020) leaves in the hands of the referee of a match its suspension due to force majeure, which would be the case to apply if a crash is suspended shortly before its start due to weather issues.
Article 240 of said Regulation specifies that “in any case, the arbitrator will weigh such circumstances according to their good judgment, always trying exhaust all means for the meeting to take place or continue ”.
For this, the referees designated for the match in question must “appear on the field with a minimum advance of an hour and a half, in order to recognize it, examine its conditions and take the decisions it deems pertinent so that the deficiencies “that they may notice are corrected.
In case of suspension before the match, Real Madrid could recover the sanctioned Carvajal if on the new date he had served his punishment
This situation would occur, for example, in the Osasuna-Real Madrid scheduled for 9:00 pm today if LaLiga, as has happened in other matches, such as Atlético-Athletic, does not request its suspension from the Spanish Football Federation beforehand. Let us remember that the meeting will be directed by the Riojan collegiate Soto Grade.
And at the point of suspension, it is advisable to bear in mind what is specified in article 242.3 with respect to the players who can play the match on the day it is “rescheduled.”
And both Osasuna and Real Madrid could line up the players who can sign from now until the new match date
“In the event that due to suspension of a meeting before its start, it must be held on a new date, The players legally registered on the new date may line up on the celebration date in which the postponed meeting is held ”. That is to say that in principle Real Madrid could get Carvajal back, sanctioned for accumulation of warnings for the El Sadar clash, if from the moment of suspension and the dispute of the match the white team played another league match in which the full-back fulfilled his accumulation sanction.
And if the clash is suspended before its start, both Osasuna and Real Madrid (or the clubs that are in this situation) they could line up on the new date set for the dispute of the match to those players who will sign from the moment of suspension until its dispute, if the case were to close any reinforcement. Taking into account that we are fully in the winter market, this is a possibility with a view to becoming a reality.
