who was the referree called red flag

I’m not sure which referee you mean by “red flag,” because that could refer to a nickname, a viral clip, or a specific match controversy. The closest match I found was coverage of FIFA’s handling of Folarin Balogun’s red-card suspension, but none of the sources clearly identify a referee called “Red Flag”.

Most likely interpretations

• A referee criticized for a bad call.
• A referee nicknamed “Red Flag” in a forum or social post.
• A specific soccer, basketball, or wrestling reference that got paraphrased.

What I can confirm

• Recent reports focus on Folarin Balogun’s red-card suspension and FIFA’s decision to lift it, not on a referee with that exact nickname.
• One source mentions a former Premier League referee discussing VAR and red-card procedure, but not a referee literally called “Red Flag”.

Best next step

Send the sport, match, or a quote from the post, and I can identify the person more precisely.
