how long will cesar montes be out of the world cut

César Montes is expected to miss one match for Mexico after the straight red card, which means he should be back for the next World Cup game unless FIFA adds extra punishment.

What the reports say

• The immediate ban is a one-match suspension under FIFA’s disciplinary rules.

• Several reports say that means he sits out the next match against South Korea/Czechia depending on the match schedule referenced in the article, then returns afterward.

• The only caveat is that FIFA can review the incident and extend the ban, though the coverage suggests that looks unlikely because it was treated as a tactical foul rather than violent conduct.

Quick takeaway

So the safest answer is: likely just 1 game out.

TL;DR: Montes is probably out for a single World Cup match, not the rest of the tournament, unless FIFA decides to make it longer.
