The Scrum cap (also known as a "rugby yarmulke") is a form of headgear used by rugby players to protect the ears in the scrum, which can otherwise suffer injuries leading to the condition commonly known as cauliflower ears.
A simpler alternative to a cap, and used by many players, is a thin strip of foam or cloth and electrical tape wrapped around the ears like a head band.
