In a state where the Gators , Noles and Canes vie for college football supremacy, an elementary school student in Florida recently showed up to class in a homemade T-shirt design bearing his allegiances to the University of Tennessee — and he was teased because of it.

Now, the boy’s hand-drawn U.T. design can be worn by fellow Volunteer fans clad in orange.

When the university learned of the bullying episode, which was shared by the boy’s teacher, Laura Snyder, in a viral Facebook post, it began offering replicas of the T-shirt for sale at U.T.’s online campus store. “Now you can share in this student’s Volunteer pride by wearing his design on your shirt too,” the store website said.

Proceeds from the shirt’s sale will be donated to the national group Stomp Out Bullying, according to the university , whose online campus store received so much traffic after promoting the shirt, it said, that the website crashed.

A university spokeswoman said Monday that more than 16,000 shirts had been pre-ordered.

Ms. Snyder is a fourth-grade teacher at Altamonte Elementary School in Altamonte Springs, Fla., an Orlando suburb.
