The International Football Federation (FIFA) has decided to keep the May 15 deadline for all 32 teams to submit their final rosters for this year's World Cup in Germany.
FIFA said in a statement that the decision is intended to allow players adequate recovery time, and injured players could be replaced after the deadline "following a specific procedure."
Several coaches had lobbied for the deadline to be extended ahead of the World Cup, which starts June 9 in Germany. Many of the top players also take part in European football's Champions League and UEFA Cup which do not end until late May.
FIFA also said that every player, coach, and official would be required to sign a declaration before the tournament pledging not to take part in illegal gambling on the games. The governing body also refused to allow more than six substitutions in friendly matches played before the World Cup.
