The league has put out an update on the 2021 season.
The May 22 start date has, obviously, been delayed. There are no further details in this update but it also mentions that "We will share an update with you on May 15 regarding our 2021 season ensuring that our Supporters and Fans will be the first to know."
I have heard rumours that the season will start in June / July with a Winnipeg bubble but those are just that, rumours.
