Not that it matters with only one game left in the season, but...
TSSAA does not care about the "soft red"/"hard red" distinction. The manner in which the ejection occurred is the issue. To be fair, soccer is the only sport besides football (of course) that has the lesser one-game suspension possibility. But that is ONLY invoked when an ejection occurs because of the denial of a goal-scoring opportunity. To be clear, under TSSAA rules, two yellows for dissent -- a "soft red" -- is a 2 game suspension. Under TSSAA rules, two yellows for anything (which results in ejection) is a 2-game suspension.
However, commit the straight-red card offense of denying a goal-scoring opportunity, and this is the only case where a player sits out for only ONE game.
