The XFL has filed for bankruptcy, almost certainly spelling the end of the second iteration of the league.

The eight-team professional football league, conceived by World Wrestling Entertainment chairman Vince McMahon as an out-of-season competitor to the NFL, had canceled the rest of its return season last month because of the coronavirus pandemic. It suspended operations and laid off its employees on Friday.

The league said on Monday in a news release that it wasn’t insulated “from the harsh economic impacts and uncertainties caused by the COVID-19 crisis.”

“This is a heartbreaking time for many, including our passionate fans, players and staff, and we are thankful to them, our television partners, and the many Americans who rallied to the XFL for the love of football,” the league said in its statement.

The XFL had eight franchises this season and played five games out of a planned 10-game schedule. It drew solid TV ratings early on and had deals with ESPN and Fox. But spring football is a difficult challenge, as the Alliance of American Football found out in 2019, not lasting a full season.

The XFL also played one season in 2001.
