NEW YORK -- The National Hockey League announced today that, effective with tonight's games, the League will be using game pucks without the imbedded tracking technology. The decision was made after concerns were raised about the puck's performance during the first few days of the 2020-21 season. A review by the League determined that the first supply of 2020-21 pucks did not receive the same precise finishing treatments during the off-season manufacturing process as were used during the 2020 Stanley Cup Playoffs. It is expected that a new supply of the League's "tracking pucks" will be available soon and, after undergoing appropriate quality control testing, will be back in use for all games. In the interim, the League will use the official game pucks from the 2019-20 season and will continue to utilize Player tracking technology for all games.
