During a scrimmage match earlier this month between two schools in Walker County, 18-year-old Seth McGee became the hero of the night when he scored a touchdown for Ridgeland High School.
Seth was handed the ball during the final play and ran the field as his entire team cheered him to the end zone.
"We had no idea that he was even going to be able to play," his sister, Faith McGee, told InsideEdition.com. But suddenly, from the stands, she and her dad saw Seth starting to run.
"It just happened really fast," she said. "I was crying of course."
Afterwards, her brother was brimming with pride.
"He was just so excited," Faith, 20, said. "He had the biggest smile on his face I've ever seen. He was saying, 'Did you see it? I did it!' He was on top of the world."
Even the opposing team was happy to see him complete the 65-yard run. The video shows rival players running alongside him and offering him their congratulations.
"The sportsmanship was incredible," said Ridgeland High School's athletic director and assistant principal Robert Stinson. "There was not a dry eye there."
Stinson told InsideEdition.com that the teen is highly active in student life and with the school's sports teams, and introduces himself to incoming freshman every year.
"Seth is beloved by our students," he said. "They really rally behind him."
When coaches saw Seth playing harder than ever during the game last week, they decided to pass him the ball and let him have his chance in the limelight, Stinson said.
His big sister couldn't be prouder.
"As his older sister, I know he might not accomplish things others can," she said. "It's really, really special to see him being treated as an equal. That's what we've always wanted."
