Major League Soccer’s primary transfer window officially opened on Tuesday, allowing teams to acquire new players through international transfers or trades within MLS.
This year the primary transfer window runs through May 8. Any transfers not completed during the primary window can take place during the secondary transfer window, which runs from July 10 to Aug. 9.
- MLS Primary Transfer Window: Feb. 14 – May 8, 2017
- MLS Secondary Transfer Window: July 10 – Aug. 9, 2017
Clubs can publicly announce transfers and trades outside of these two windows, but a player cannot officially be added to a team’s roster until his International Transfer Certificate is transfered, which must happen within one of the two windows.
During the MLS regular season, intra-league trades involving players can only happen within the windows.
However, teams can still make trades that don’t involve players—exchanging draft picks, roster spots, allocation money and other assets—outside these two windows. Clubs may also transfer or loan their players to non-MLS clubs at any time.
