The Euro Hockey League is considered to be something of a pioneer when it comes to rules and regulations. The tournament has introduced various test rules which have now been adopted by the global game, with the "Self Pass" - which allows players to dribble with the ball from a free hit rather than passing it - being arguably the most revolutionary. The 2009-2010 Season saw the introduction of the "Own Goal" trial, which meant that defenders and goalkeepers could no longer force the ball into their own net when an opposing player has hit the ball from outside the circle. The first ever own goal in hockey arrived during Round 1.1, when Atletic Terrassa's Xavi Ribas accidentally deflected into his own goal during their match against Reading HC of England. In total, five own goals were scored during the 2009-2010 season. [2] [1]
