In part, the guidelines state that prospective student-athletes who “entered an agreement with, competed on or received compensation from a team that participates in a league with minimum compensation that exceeds actual and necessary expenses” will not have their college eligibility reinstated. The document lists MLB, NBA, NFL, Premier League and WNBA as examples of such leagues, but other top basketball leagues globally could also qualify.

“Actual and necessary expenses continue to be a factor in a prospect’s eligibility, but as part of that broader effort to update preenrollment rules, the NCAA also identified several international leagues in which participation by a prospect is likely to result in violations of NCAA rules and a loss of eligibility,” an NCAA spokesperson said in a statement to SI. “The Association is modernizing the rule book in several ways to ensure college sports are played by college athletes and not used as a fallback for professional athletes, and the age-based eligibility model now under consideration is designed to address many member schools’ concerns regarding eligibility.”
