[Q]: Paragraph: Eleven goaltenders have scored a total of fourteen goals in National Hockey League ( NHL ) games . A goalkeeper can score by either shooting the puck into the net , or being awarded the goal as the last player on his team to touch the puck when an opponent scored an own goal . A goal scored by shooting the puck is particularly challenging as the goaltender has to aim for a six - foot - wide net that is close to 180 feet away , while avoiding opposing defencemen ; in the case of own goals , the combined circumstance of the own goal itself in addition to the goaltender being the last player to touch the puck makes it a very rare occurrence . Of the fourteen goals , seven were scored by shooting the puck and seven were the result of own goals .
