FIFA has released a timetable for the 32 World Cup nations to set their 23 man rosters.
The 30 man provisional roster must be turned in by midnight on May 11 and FIFA will publish the list on May 13th.
The final 23 man rosters must be submitted by June 1 and FIFA will release them on June 4. After this date only seriously injured players can be replaced.
So circle June 4 on your calendar, or just draw a frowny-face in anticipation of Brian Ching making the team.
