On bruntyboys post about the « orange » cards and not going to OFRs,
I think in the end we will have to change to the protocol used in the World
Cup to avoid this potential inconsistency. I think I read somewhere that the
Bundesliga attemped to avoid OFRs when they started with VAR but abandoned
it after a few weeks for this very reason.
Also I do think it is possible to give a yellow card after an OFR. I seem to recall
in the World Cup Ronaldo was given a yellow after Diedhiou was asked to review
a slap (for a possible red card) and he deemed it worthy of only a yellow card. So certainly
it appears to have been permissible under the protocols used at the World Cup last year.
