(1) "Participating in sports or athletic events" refers only to the services performed by athletes as contestants in sports or athletic events and not to the services performed by managers, coaches, trainers, referees, umpires, scorers, groundskeepers or other individuals who are not contestants.
(2) An individual shall be deemed to perform "substantially all" of his or her services participating in sports or athletic events if such participation accounts for seventy-five per cent or more of total services performed during the base period.
(3) A "sports season" shall be deemed to begin on the date that scheduled training begins and to end on the date on which all related sports activity ceases.
(B) The period between two successive sports seasons or similar periods shall begin with the Sunday immediately following the date on which the sports season ends and shall continue through the Saturday following the date on which the next sports season begins.
(C) A claim for benefits shall be disallowed when the individual has reasonable assurance of employment with either the same employer or a different athletic employer for the next sports season.
(D) When an athlete performs services in nonathletic employment in addition to athletic employment, and the athlete has reasonable assurance of employment for the next sports season, claims for benefits shall be disallowed between sports seasons even if the nonathletic employment was sufficient to establish a valid application for determination of benefit rights.
