Peyton Manning's whole family was cheering him on after a fourth quarter touchdown that put the Broncos 12 points ahead of the Panthers during Super Bowl 50 Sunday night.

Everyone, that is, except his brother.

A zoomed in shot of Eli Manning showed the New York Giants quarterback with a blank expression, surrounded by his celebrating family.

The image was widely shared on social media.

Could a little sibling rivalry be to blame?

The Broncos' 24-10 win over the Panthers gave Manning his second Super Bowl ring, tying him with his younger brother.

We may never know why Eli had the confused look on his face, but there has been lots of speculation on Twitter.

"Look closely at Eli Manning's face - he's hearing the call of the Dark Side," @SithInc tweeted.

"This is the face of a man who prolly just bet a lot of money against his brother," Trey Hill tweeted. 

One thing we do know? It was awkward.
