Here's the release:
Applications for retroactive TUEs are limited to medical emergencies and ‘exceptional circumstances’. Exceptional circumstances are those in which “there was insufficient time or opportunity for an applicant to submit, or a TUE Committee to consider, an application prior to Doping Control.”
According to WADA guidelines for TUEs, exceptional circumstances may include those where a normally healthy player is suddenly affected by a significant medical condition some days prior to an event, and is unable to request a TUE within the allotted time to enable the TUE to be granted.
Thus, players may apply for a TUE retroactively in the event that they need to use a prohibited substance (for valid therapeutic reasons) in order to play in an event. The TUE application form will shortly be updated to reflect this change.
