What happened: Kwaku Agyabeng was shown a red card in the 38th minute of the Colorado-Sporting Kansas City match. The score remained 0-0 at the time of the dismissal, leaving Sporting KC to play the rest of the match a man down.

Why it matters: Playing over an hour with a numerical disadvantage in a scoreless match significantly raises the difficulty of securing a result. The sending-off forces an in-game reshuffle and puts extra defensive strain on the remaining ten players.

What to watch: Watch how Sporting KC organizes with ten men and whether Colorado can capitalize on the man advantage before the match ends.
