Trey Erwin watched the Orange and White game from the 50 yard line in a skybox.
"Today has been amazing. I've been blessed so much. It's crazy," said the 15-year old Collierville teenager.
The high school football player got the VIP treatment.
He went inside the locker room with Head Coach Derek Dooley, threw a few passes with quarterback Tyler Bray, and got hugs from the cheerleaders.
"Meeting them was incredible," he said.
But when Trey woke up this morning, he didn't know if he could make it through the big day ahead. He's battling Stage IV pancreatic cancer.
"I'm not 100% but I've been fighting," Erwin said.
Erwin was diagnosed a little more than a month ago. He's undergoing chemo and often doesn't have all his strength.
When the Young Alumni chapter at UT heard that it was his dream to be a Tennessee Volunteer, they decided to make it happen.
"My faith in God is what's getting me through... Prayer works," he said.
His friends and family have created the #PrayforTrey hashtag on Twitter.
"There are "Pray for Trey" signs all over school. Everyone at church is wearing t-shirts, bracelets. It's gone viral," said Trey's best friend, Cody Jordan.
"This morning I put it out [on Twitter]. I said he doesn't have the strength to get out of bed this morning please pray for Trey to get out because we know we have a full day ahead... And as it turns out he has strength, he has energy. He's had a great day," said Trey's mom, Lisa Erwin.
The Young Alumni Association named him an honorary UT alum and recognized him at a lunch.
It's a title that he's hoping to give up and be able to attend UT himself. But, doctor's have only given him 11 months to live.
His family isn't letting that stop them from fighting.
"Those are just numbers that someone wrote down. We believe that our God is in control and he sets parameters on death. We're believing in healing," said Lisa Erwin.
His friends that attend UT painted the Rock, a message board for students, with "Welcome Erwins, Pray for Trey." It also had the link to his Caring Bridge website. Friday at Collierville High School, where Trey attends, they held a pep-rally for him. It was his first day back since doctors diagnosed him.
There, the mayor of Collierville declared his birthday, July 31st, Trey Erwin Day.
