How does yellow card accumulation work in the playoffs? I can find the rules for the regular season on the MLS site (5 cards over the course of the season will essentially earn a suspension and a player in peril (4 cards) can get one taken off the total if they go a number of games (4 or 5 perhaps?) with a clean slate. But I can't find any rules listed that specify what the rules are for the playoffs. During the Chivas match in the HDC, both Razov and Thomas (who were each booked in the first game at Rio Tinto) received a yellow and the announcers said that they would be forced to sit out the western final if Chivas advanced. (Presumably either for their second straight playoff game with a yellow, or 2 total throughout the playoffs.) So far RSL has had Beckerman and Williams booked in game 1, and Borchers, Kovalenko, and Mathis booked in game 2. Does this mean they are all in 'yellow peril' for Saturday's match, or is it possible that only those booked in game 2 are in peril this weekend? I'd hate to see some of the players who had strong contributions to get us this far be unavailable for the final should we get past the Red Bulls.
