It's the fact that he was treated on-field, not that it took more than 10s to leave. Therefore the minute off the FOP is transferred to the sub coming on... No?There is an exemption if it's an injured player that's being subbed off.
"The referee may decide not to apply the ten-second time limit, including when:
a player’s injury clearly prevents them from leaving the field within that time"
I'm thinking the same thing happened in the Prem already this season and it caused a stir then too. Can't recall the game
Anyway, maybe I got it wrong. I found it all a bit all over the place, but first game back so I was rusty. It feels like constantly raising one's profile when I prefer to stay anonymous if I possibly can
