The CONCACAF Champions League will expand from 16 teams to 50 in 2023-24, restore its group stage, switch to a regionalised first-round alignment, and fill 11 of 16 berths in the knockout stage from North America. The championship match will switch to a single knockout from a two-leg, home-and-home format.

The Confederation of North American and Caribbean Association Football launched the Champions League, modeled after Europe’s Champions League, for the 2008-09 season to replace the CONCACAF Champions Cup.

CONCACAF announced in January 2017 that it was trimming the competition from 24 teams to 16 for the 2017-18 season. It eliminated the group stage, shortened the length from eight months to four and delayed the start from August to February.

That format will remain in place for 2021, 2022 and 2023, and the draw for this year’s tournament is scheduled for February 10.

Under changes announced on Thursday, the regionalised group stage will take place each fall with 20 teams from the United States, Mexico and Canada split among four North American groups of five teams each; 20 teams from Costa Rica, Honduras, Panama, El Salvador, Guatemala, Nicaragua and Belize split among four Central American groups of five teams each; and 10 teams split into two Caribbean groups of five teams each.

The knockout stage starting in the spring will include 11 North American teams: the first- and second-place teams from each group and three other teams that advance from a play-in round.

There will be four Central American teams: the winners of a play-in round involving the first- and second-place teams from each group.

The two Caribbean group winners will meet for a berth in the knockout stage.
