BEAVER FALLS, Pa. - A 17-year-old high school student said he was humiliated when a teacher made him sit on the floor during a midterm exam in his ethnicity class — for wearing a Denver Broncos jersey.

The teacher, John Kelly, forced Joshua Vannoy to sit on the floor and take the test Friday — two days before the Pittsburgh Steelers beat the Broncos 34-17 in the AFC championship game. Kelly also made other students throw crumpled up paper at Vannoy, whom he called a “stinking Denver fan,” Vannoy told The Associated Press on Monday.

Kelly said Vannoy, a junior at Beaver Area Senior High School, just didn’t get the joke.

“If he felt uncomfortable, then that’s a lesson; that’s what (the class) is designed to do,” Kelly told The Denver Post. “It was silly fun. I can’t believe he was upset.”

Vannoy was wearing a No. 7 Broncos jersey on Friday, because he is a fan of John Elway, the Broncos’ retired Hall of Fame quarterback.

Vannoy said he was so unnerved he left at least 20 questions blank on the 60-question test, and just wants out of Kelly’s class because he’s afraid the teacher won’t treat him fairly now that the story reached the media.

“I’m going to have to deal with him for two more nine weeks (school quarters) and he’s going to want revenge somehow,” Vannoy said Monday. “I took the test. I’m shaking. I’m furious. I didn’t know what to do.”

Kelly, who wore a Ben Roethlisberger jersey Friday, and his principal, Thomas Karczewski, didn’t immediately return messages left on their school voice mail Monday.

Big Beaver Falls Area School District Superintendent Donna Nugent said she was aware of the situation, but said confidentiality rules prevent her from commenting specifically.

“We’ll take whatever action we need to in order for the student to feel comfortable,” Nugent said.
