• Bills wide receiver Isaiah McKenzie scored a touchdown on Thursday against the Rams.
• After the score, McKenzie screamed into the camera: "It's a boy!"

The Buffalo Bills dominated the Los Angeles Rams at SoFi Stadium on Thursday night to kick off the NFL season.

Early in the second half, Bills quarterback Josh Allen connected with wide receiver Isaiah McKenzie for a seven-yard touchdown that would put Buffalo ahead for good.

While celebrating the touchdown, McKenzie yelled into the camera, "It's a boy! It's a boy!"

As it turns out, McKenzie was breaking news to his family watching at home.

McKenzie's sister is pregnant, and on the field in Los Angeles, in front of a national television audience, her brother had just pulled off one impressive gender reveal.

The Bills put out video of McKenzie's family watching from home after he scored. "Do it right now!" someone can be heard excitedly saying after McKenzie reached the end zone.

That he did.

After the Bills made the gender reveal public, one fan asked a critical question: What was McKenzie's plan had he not reached the end zone on Thursday night?

McKenzie delivered a simple answer.
