(JTA) – A South Carolina teenager said he was beaten by teammates on his middle school’s football team because he is Jewish.

Caspian Driscoll, 15, of Fort Mill told NBC-TV Charlotte that the incident occurred on Oct. 10 on the team bus.

Driscoll reportedly asked his teammates to be quiet so he could wish his grandmother a happy birthday by cell phone. They shouted anti-Semitic insults, he told NBC Charlotte, adding that they had made similar insults in the past.

When he attempted to get off the bus in the parking lot, Driscoll said a teammate pushed him back in his seat and told him to “’Sit down, you stupid Jew!” That sparked a fist fight, which led to a two-day suspension from school for Driscoll and three other students and being kicked off the team for the rest of the season.
