To release the bowl in lawn bowling can you have your left foot on the mat and kneel on your right knee?

In lawn Bowling, the player must have their foot on the mat while delivering the bowl. It is not permitted to kneel on one knee during the delivery; both feet should be in contact with the mat until the bowl is released. Therefore, having your left foot on the mat and kneeling on your right knee would not be allowed. Proper technique requires standing with both feet on the mat for a legal delivery.
