how was the rugby ball originally made
An opponent can not run into the goalkeeper if the goalkeeper has possession of the ball. Nor can an opponent run into a keeper if the ball is not within playing distance of the two players. Under no circumstances can a player run into the keeper intentionally, but might only do so in the course of fairly playing the ball. If a keeper has the ball after a catch, and a player runs into or tackles him, it is automatic red card.
