More than 150 friends, coaches and classmates held a vigil outside Cook Children's Medical Center in Fort Worth Wednesday night.
There, 16-year-old Sammy Ramon-Hunter, Jr. is recovering from complications after his fifth heart valve replacement surgery since he was born.
It was difficult for blood to get to his lungs -- a problem that started when he was 2 months old, when FOX 4 first shared his story.
Sammy is now 16 and the team manager for the Haltom High School football team.
His teammates signed helmets and poster board and joined hands to say prayers for his recovery.
The teen's family says he opened his eyes Wednesday, which is a good sign.
Classmates plan to wear orange and black Thursday in his honor. They're calling it King Sammy Day.
