There are no credible reports or official statements from CBS Sports News, Tony Romo, or any reputable sports news outlet confirming that Tony Romo called Patrick Mahomes “ungrateful and fake” or humiliated him on set.

Fact Check:

Tony Romo is a well-known CBS Sports analyst and former NFL quarterback, respected for his insightful and positive commentary.
There is no evidence—no video, transcript, or article from legitimate sources—showing Tony Romo making such comments about Patrick Mahomes.
CBS Sports and its analysts maintain high professional standards and do not engage in personal attacks or public humiliation of athletes.

Why This Is Important:

False or sensational headlines can quickly spread on social media, but they are not always true.
Reputable broadcasters and analysts like Tony Romo are careful with their words, especially regarding high-profile athletes.

How to Verify Sports News:

Check multiple trusted sources (CBS Sports, ESPN, NFL.com, etc.).
Look for direct quotes or video evidence from the broadcast.
Be cautious of headlines that seem designed to shock or stir controversy without proof.

Conclusion:

This story appears to be fabricated or a rumor with no basis in verified journalism.
