FC Dallas has just been kicked out of the MLS' restart tournament ... citing a major coronavirus outbreak within the organization.

The league is hosting its MLS Is Back tournament at ESPN's Wide World Of Sports Complex in Orlando starting this week ... as a way to pick back up where things left off in March.

But, the bad news for FCD -- the team had 11 cases (10 players and 1 coach) test positive while in Orlando ... forcing the MLS to step in and stop the team from participating.
