On advice of the Return To Play Task Force, the AHL has pushed the start date for the 2020-21 season to no earlier than December 4. This is no guarantee that the season will start on that date, of course. More could change in that time, given how fluid the COVID situation is and the unique geographic and economic concerns of the league.
Here's the release:
American Hockey League President and CEO Scott Howson has announced a revised start date for the 2020-21 AHL season, as approved by the league’s Board of Governors during its 2020 Annual Meeting held today via conference call.
