红牌出现 比赛形势急转直下（红牌一出，战局瞬间失衡）

Preparing Chinese headlines

I’m considering six alternative phrasings in Chinese for various contexts such as headlines, commentary, and social media. I want to keep them brief and clear. I also need to ask about the tone and sport, as “red card” typically refers to soccer. I’ll provide a variety of options that reflect the dramatic shift a red card brings to the game, and I’ll include some longer sentences too. Additionally, I’ll inquire if specific teams or minute details are needed!
