Wow, if a player has two, both yellows in a match are not counted? I thought it would only be one not counted (or unfairly, none).
So, if he gets a 10th yellow in the Hull match, he should deliberately get a second yellow (=sending off) in the 94th minute of that match (with 30 seconds left in the match), and only serve a one match ban for the subsequent red, instead of 2 matches for 10 yellows.
