Short summary

The NCAA Division I Council adopted a new age-based eligibility model replacing the Four-in-Five Rule, allowing five seasons within a five-year window starting at age 19 or first enrollment, while eliminating redshirts and most waivers. Student athletes filed a class action lawsuit (Campbell v. NCAA) alleging the rule is an unlawful restraint of trade under the Sherman Antitrust Act, arguing eligibility now gates NIL and revenue-sharing compensation. The outcome could force another major revision of NCAA eligibility rules with significant financial implications for athletes and institutions.
