I just had a minor panic when I saw it pointed out elsewhere that we made six subs, none of them for concussion . Was imagining the meltdown when we have to forfeit the game.
But apparently if a team has a concussion sub, the opponents get an additional normal sub to stop any advantage of an extra fresh player. Didn’t know that.
And I’m sure we didn’t mind being able to stop the game for 30s deep in added to add the sub.
