The crash ball is an attacking tactic in rugby league and rugby union where a player receives a pass at pace and runs to the opposition's defensive line. The crash ball runner attempts to commit two or more opposing players to the tackle, then attempts to make the ball available to teammates by offloading in the tackle, performing a quick play-the-ball in rugby league, or recycling the ball quickly from the ruck in rugby union. By committing players to the tackle, the crash ball runner creates holes in the opposition's defense, thereby creating attacking opportunities for teammates.
