World Rugby implements lower tackle height for grassroots rugby

World Rugby will outlaw tackles above the base of the sternum in grassroots rugby starting in July. National unions can choose to set the upper limit for tackling at either the base of the sternum or the waist. The law follows a multi-year trial in Britain and Ireland, which showed reductions in concussion incidents. A similar rule will be tested at the World under-20s Championship in Georgia this summer, potentially influencing elite rugby. The law's final impact on professional play is yet to be determined, pending results from the under-20s trial.
