"Within seven days of the date of the ITC request, the former association shall, by using the appropriate selection in TMS, either: a) deliver the ITC in favour of the new association and enter the deregistration date of the player; or b) reject the ITC request and indicate in TMS the reason for rejection, which may be either that the contract between the former club and the professional player has not expired or that there has been no mutual agreement regarding its early termination. 5. Once the ITC has been delivered, the new association shall confirm receipt and complete the relevant player registration information in TMS. 6. If the new association does not receive a response to the ITC request within 15 days of the ITC request being made, it shall immediately register the professional player with the new club on a provisional basis (“provisional Annexe 3 59 registration”). The new association shall complete the relevant player registration information in TMS (cf. Annexe 3, article 5.2 paragraph 6). A provisional registration shall become permanent one year after the ITC request. The Players’ Status Committee may withdraw a provisional registration, if, during this one-year period, the former association presents valid reasons explaining why it did not respond to the ITC request."
