足球回避条款有多久？
其实这个内容在 2020/21 赛季开始就已经有了，只不过没被太多人关注到而已…… 规则中叫做球员“保护性条款”（Protection Clause），在联赛和杯赛的资格赛、小组赛中适用(1)，而在淘汰赛中不适用(2)。
规则原文如下：
(1) The following provisions apply in the Qualifying Rounds， First and Second Round (if applicable)， Group Stages of the EFL Cup， FA Community Shield，FA Cup and CLUB CUP COMPETITIONS. a If an Player’s International or Club Team Participation may be restricted by his National Association，National Federation，Club或Club's League because of the date upon which he was registered for the Competition concerned 他应遵守国际足联和/或相关国家或地区联合会的相关规定 b Players who are under-18 on Registration day shall not play any part in the Competition if they have played more than seven competitive matches (i) during the current season(ii) between 6th October and 30th June preceding the start of that Season，or (iii) since their last registration in accordance with Article 39(a) above. c In relation to players whose international eligibility is currently restricted， clubs must inform FIFA whether their player has played competitive games. d For the purposes of this Protection Clause a match does not include： （i） Training； （ii） Matches in Tournaments or Competitions arranged solely for the benefit of Under－18 players； or （iii） Games in the Under——18 Comprehensives Tournament organised by a League or County F.A. e Clubs must keep a record of all Protected Players within their squads．This information should be provided to the Premier League and/or the EFL when requested．The League will notify relevant competitions as appropriate.
(2) Where there arises any question regarding the application of this Clause the matter shall be referred to The Board of Directors of The League where a determination shall be given as soon as reasonably practicable after receipt of such reference. Such decision shall be final and binding on both parties. Provided always however that no such reference shall affect the responsibility of the respective Associations and Bodies to comply with the relevant Regulations of FIFA and/or IFAB.
可以粗略地理解为：
1、如果因为国家队以及俱乐部的原因，该球员可能会被禁止参加
