Jordy Robertson initially predicted the surgery would take between 8-10 hours. He said the liver is working, but the next few days will be crucial.
Jarrius, who signed a "contract" last year on "Good Morning America" to become an official "hype man" for the Saints, has played a big role with the organization.
Several Saints players tweeted their support for Jarrius Sunday afternoon, including quarterback Drew Brees.

Jarrius, 15, battles biliary atresia — a chronic liver disease that affects his physical growth. He has been in and out of hospitals since receiving a liver transplant when he was 1. He spent a year of his life in a coma, according to ESPN.com.
