KANSAS CITY, Mo. -- A young New Orleans Saints fan (and newest team member) made his way to the metro this weekend.

14-year-old Jarrius Robertson was greeted by Chiefs fans when his plane landed, he signed autographs at Arrowhead Sunday, and he welcomed players onto the field.

The Saints' youngest player doesn't even play football, but he's become the new face for Who Dat Nation.

14-year-old Jarrius Robertson battles a rare chronic liver disease that stunts his growth. He met some of the Saints players during one of his many hospital stays and the team loved him.

This week, "Lil JJ" appeared on Good Morning America, where Drew Brees, Cam Jordan, and head coach Sean Payton signed Jarrius onto the team so he could travel along and help with social media duties. Jarrius said he'd had a busy schedule in Kansas City.

He "signed a lot of autographs, took a lot of pictures, and ate BBQ!"

His father Jordy Robertson said, "It's been a tough ride but it's keeping him strong, keeping him going."

Jordy Robertson traveled with his boy and the team for Sunday's match-up against the Chiefs.

"We didn't know when we got off the bus Kansas City fans would be giving up open arms. I want to thank Kansas City for that. They were there waiting for us!"

Robertson said reaching people here in the metro, and anywhere, is the goal; helping others going through the same medical struggles.

"If we can touch lives in Kansas City, we're here to touch lives."

While Jarrius had fun Sunday cheering on his boys, doing social media stuff, and enjoying Arrowhead, his dad said it's really about sharing this message: "It takes lives to save lives. That's where we're sticking with. That's his motto and that's what he made up."

Jarrius is on a waiting list for a much-needed liver transplant. He explained to FOX 4 that he's got a wish list, some of which he's already received, but he's also holding out for some of the big stuff: "Mercedes Benz for when I get older, a helicopter so I can beat all the traffic after the Saints games, and an iPad!"

A GoFundMe page has been set up to help Jarrius's family with his medical bills.
