Bahraini football teams will be authorised to make five substitutions instead of the current three.
Bahrain Football Association (BFA) announced the new regulations, endorsed by Fifa, taking players’ safety into account.
The teams are gearing up for the resumption of the 2019-20 league football season on August 7.
Fifa had earlier proposed increasing the number of substitutions in 90 minutes from three to five – with a sixth in extra time of knock-out games – to help combat injuries with more games being played in a shorter period of time.
