DUBLIN (Reuters) -Concussion rates fell 33% in the Irish men's rugby All-Ireland League during a two-season trial period of a new law lowering tackle height, the Irish Rugby Football Union said on Wednesday, describing the results as "a landmark reduction".

The IRFU joined a World Rugby trial of lowering tackle height below the base of the sternum in its community game in 2023, including the men's and women's AIL competition that is one rung below the four main professional provincial teams.
