Moderator's note: The announced changes affect Outdoor and Indoor hockey. There has been particularly lively discussion of the 'hand on floor' change for Indoor, which now has its own thread in The Indoor Umpiring Corner. Discussion of the Outdoor rule changes continues below. Diligent 3-Jul-12 FIH have published advanced notice of the proposed changes to the rules for 2013. Here they are (original document here): NB. This is advance notice only. The final version of the new rules, with the exact wording of the changes, has not yet been published. It is expected in September 2012. However, I'm sure that there will be no other significant changes made between now and then.
