who's red card was earliest in a first round game

Question

As a booby prize in the world cup sweep stake I'm running at work, to not dissappoint the people with bum teams, I am paying out on the QUICKEST SENDING OFF and Number of Yellow Cards the team picks up in the first round. I know it's not the first round is not finished yet, but I've drawn a blank on the net so far on on finding any statistics. Can anybody help please?
