The NEAUX PROS Act prohibits professional athletes from competing in college sports, establishing penalties for institutions that violate this rule. The bill guides institutions in determining a student-athlete's professional status and allows for current competitors to transition. It also prohibits private legal action against institutions, criminalizes knowingly recruiting professional athletes, and exempts institutions from criminal liability. The bill will enforce amendments in athletic recruitment and impose criminal penalties for violations. It will take effect at the start of the first academic year post-enactment for covered institutions, with criminal penalties applicable to conduct after enactment.
