Hello, what is the length of suspension for a player who has been suspended following a red card?
Does the suspension relate to the league match or official matches or to the day?

It says on the player details timestamp until the player is suspended. He can't play in any matches until then.

Andre Malles: It says on the player details timestamp until the player is suspended. He can't play in any matches until then.

You don't understand the question!

And yet he gave you the right answer.
Your player is suspended, so he can't be in any starting XI until the date indicated. Regardless of the type of match

Magpie: Et pourtant, il t'a répondu correctement.
Ton joueur est suspendu, donc ne peut intégrer aucun onze titulaire jusqu'à la date indiquée. Peu importe le type de match

Magpie, sorry but no, Andre Malles didn't answer my question.
He just repeated what's already written on the player's form: the end date of the suspension and that the player can't play until then.
I already knew that, but that's not what I was asking. My real question is: how is the length of a suspension determined after a red card?
Is it :
a fixed duration (3 days, 1 match, etc.)?
based on a certain number of official matches?
linked solely to the league, to all official matches, or just to the calendar?
In short, I'm not looking for the date, I'm looking for the logic of the calculation.

It's the same for everyone

3 days, from the moment it is suspended

And regardless of the type of match, the suspension applies equally to all matches.

THE MAN SAYS...
A wink for the 40+ 😁

Jallow: Magpie, désolé mais non, Andre Malles n’a pas répondu à ma question.
Il m’a juste répété ce qui est déjà écrit sur la fiche du joueur : la date de fin de suspension et que le joueur ne peut pas jouer jusque-là.
Ça, je le savais déjà, ce n’est pas ce que je demandais. Ma vraie question c’est : comment est déterminée la durée d’une suspension après un carton rouge ?
Est-ce que c’est :
une durée fixe (3 jours, 1 match, etc.) ?
basé sur un certain nombre de matchs officiels ?
lié uniquement au ch...

You're kinda right as I didn't say for how long a player is suspended, but where to check until when he's suspended. Sorry, red card suspension lasts approximately 72 hours from the moment a player receives a red card, I think. But I think it was clear what I meant regarding the second question, ie. can't be picked for any match while he's suspended.
Please have in mind that we can only read what you wrote and in my case that us English translation of what you wrote (I know a tiny bit of French and I don't think anything was lost in translation this time), so how could I know that you meant how is the length of suspension determined (it's same for everyone as answered already by another user).

I think he's asking whether the red card jumps in the event of a federation/is selection.

To be or not to be
In short, when your player receives 2 yellow cards in 2 different matches, I think he receives a 2-match suspension, a straight red, I think, is a 3-match suspension.
It depends on the seriousness of the offence, but direct red is 3 days.

But not at all....
It's a 72-hour suspension, full stop.
As already mentioned.

A return from the federation cancels an ongoing suspension

kiki-sainté: To be or not to be
Bref quand ton joueur reçois 2 cartons jaune sur 2 matchs différents, je crois qu il recoit 2 matchs de suspension, le rouge direct il me semble c est 2 matchs de suspension
Exemple ce joueur a été exclu le 12 M. Kouha il a pris 2 matchs
C est selon la gravité de la faute mais rouge directe c est 3 jours des fois

A foul with the last defender on a striker running off alone on goal is at least a 15-day suspension 😂
