Cricket's Law 8.1 states
Two sets of wickets shall be pitched opposite and parallel to each other at a distance of 22 yards/20.12 m between the centres of the two middle stumps. Each set shall be 9 in/22.86 cm wide and shall consist of three wooden stumps with two wooden bails on top. See Appendix A.
Have there been any recent changes in this law, and if not why are LED stumps allowed in international matches? Are the LED stumps counted as "wooden", or am I completely missing something?
