Nets may be attached to the posts, cross-bars and ground behind the goals. They should be appropriately supported and be so placed as to allow the goalkeeper ample room.
Footnote: Goal nets. The use of nets made of hemp, jute or nylon is permitted. The nylon strings may, however, not be thinner than those made of hemp or jute.
