A video circulating among Giants fans on Twitter showed two people with a personal connection to rookie linebacker Tomon Fox reacting in the MetLife Stadium stands to his big hit and forced fumble in the closing seconds of a win against Sunday the Bengals. The overjoyed surprise looks and raw emotion is captivating.

“Boom!” the man said.

“That’s my baby!” the woman shouted.

Copies of the video incorrectly identified the people as Fox’s parents. They are supportive family friends who saw Fox play in person for the first time, according to an email from Fox’s mother Monica to The Post.

“I am grateful for their support of him,” Monica wrote. “Both his father, Tony Fox, and I are proud [of] him. Go Giants!!!!!!”

Fox lined up pressed against the sideline in an unusual defensive formation designed to prevent the Bengals from getting out of bounds. He looked like he was shot out of a cannon as he popped the unsuspecting underneath receiver.

“It was a good hit,” Giants head coach Brian Daboll said. “We want to make sure it’s clean. He led with his shoulder. It was good situational football.”
