(Reuters) Basketball players will be allowed to wear headgear for religious reasons now that world governing body FIBA has approved a new regulation, which will take effect on October 1.

“The new rule comes as a result of the fact that traditional dress codes in some countries, which called for the head and/or entire body being covered, were incompatible with FIBA’s previous headgear rule,” FIBA — as the International Basketball Association is known — said in a statement Thursday (May 4).

Qatar’s women’s team withdrew from the 2014 Asian Games in South Korea after being denied permission to wear the hijab on court.

The decision, which overturns a 20-year ban on religious head coverings that was originally imposed for safety reasons, was ratified by Swiss-based FIBA’s Mid-Term Congress in Hong Kong.

FIBA began a two-year revision and testing period in September 2014, granting exceptions at national level. It’s central board approved a modification to the rule after receiving a report in January.

The Mid-Term Congress singled out, as an historical moment, a test game in Iran on April 13 that featured women wearing hijabs and “marked the first time men witnessed a women’s sporting event in person.”

FIBA said the new rule, which would also allow turbans and yarmulkes, would minimize the risk of injury while ensuring the uniform was of a consistent color.

The headgear must be black or white, or of the same dominant color as that of the uniform, and the same color for all players on a team.

It must not cover any part of the player’s face entirely or partially, can have no opening or closing elements around the face and neck or pose a danger to any player.
