In order to stay tactically keen with the evolving development of our sport, it's pivotal for field hockey athletes, coaches and umpires to continually check on the changes and adjustments made to the rules. Therefore, USA Field Hockey is pleased to announce the release of the 2013 Rule Comparison Table 1.03. This document is upheld and maintained by USA Field Hockey, NCAA and NFHS games. The 2013 edition can also be found on our umpiring page which also contains links to videos of the 2013 National Rules Briefing. Please return to the umpiring page throughout the season to ensure you have the latest edition of the comparison document as well as other news and information.
