(CNN)A Tennessee high school athlete was disqualified from a volleyball match for wearing a hijab, prompting calls for a statewide rule change.
Najah Aqeel, a freshman at Valor Collegiate Prep in Nashville, was warming up for a match on September 15 when her coach said a referee had refused to let her play due to her headscarf.
The referee cited a casebook rule requiring athletes who wear a hijab to be granted authorization from the Tennessee Secondary School Athletic Association (TSSAA). Najah, 14, said she did not have authorization, but that it wasn't an issue for previous matches.
Faced with the choice to remove her hijab or sit out the match, Najah decided not to play. Most Muslim women who wear the hijab only remove it in the presence of other women or immediate family members.
"I was angry, sad and also shocked just because I had never heard of the rule before that," Najah told CNN. "The rule has no business being in the casebook. It singles out hijabis. I don't see why I need approval to wear my hijab when it is a part of my religion."
Karissa Niehoff, executive director for The National Federation of State High School Associations (NFSH), which sets competition rules for most US high school sports, told CNN that the uniform guidelines are not hard rules, and that states can make exceptions.
"We are heartbroken and deeply sorry that the young lady was disqualified from the match for wearing the hijab," Niehoff said.
"More common sense should have been demonstrated by the adults. The correct approach the referee should have taken is to have allowed the young lady to play and point out after the game that next time she needs to submit a letter."
An 'antiquated' rule
NFSH provides specific guidance on uniforms.
"The player must have authorization from the state association to wear the hijab or other types of items for religious reasons as it is otherwise illegal," according to the NFSH Volleyball Casebook.
Niehoff said NFSH is preparing to introduce new language to its casebook pertaining to religious headwear so that it will no longer be an issue in the future, unless it poses a danger to the player or other athletes.
Cameron Hill, athletic director at Valor Collegiate Academies, told CNN the school was unaware of the rule that prevented Najah from playing, and characterized it as "antiquated and oppressive."
"We want our state to make it understood that there is no need for Muslim women to get permission to wear their religious headwear," Hill said. "This rule is discriminatory and inequitable. We stand in solidarity with all of our scholars and families and their freedoms to express their religion freely and openly."
Hill said Valor Collegiate Academies has since drafted language they will propose to the TSSAA in hopes of issuing an exception to the rule.
An issue of Constitutional rights
Sabina Mohyuddin, executive director of the American Muslim Advisory Council, told CNN she is helping the Aqeel family resolve the matter. She says it's an issue of Constitutional rights.
"Why should Muslim girls, who want to follow their constitutionally protected right, h
