Sir Wayne Smith, former All Blacks and Black Ferns coach, suspects new amendments will be made to rugby's laws.

Speaking on the Between Two Beers podcast, he claimed rugby would need to 'reinvent' itself by lowering the permissible tackle height to belly-button level.

Sky Sport commentator Ken Laban says these potential changes come with 'dangerous' consequences for the future of the sport.

"It's a physical contest taking place, this encouraging them to tackle low- to me that's a reduction in the physicality and a reduction in the game's appeal, that's the danger."
