While all 27 MLS clubs have been busy building toward the 2021 season with roster moves and additions, the actual window to sign players had not yet opened.
That changes today, March 10, when the Primary Transfer Window officially begins and runs through June 1.
- Primary Transfer Window: Wednesday, March 10 – Tuesday, June 1, 2021
- Secondary Transfer Window: Wednesday, July 7 – Thursday, Aug. 5, 2021
The Primary Transfer Window was originally slated to run from Feb. 10 to May 4 but was pushed back four weeks due to the late start of the MLS regular season, which will kick off the weekend of April 17.
