The NCAA’s Legislative Council approved a proposal on Wednesday that would require student-athletes interested in testing the waters of the NBA draft to remove their name from consideration before the first day of the spring National Letter of Intent signing period.

This year's spring signing period began April 13th and closes May 18.

The deadline for players to declare for this year's draft is April 24. Players can withdraw by May 8 and keep college eligibility, provided they do not retain agents.

Until 2010, the deadline to withdraw was 10 days before the draft, which typically is in the final week of June.

Should the even earlier April deadline take effect, players whose teams make deep runs in the NCAA tournament, up to and including the Final Four, could have as little as a week to make a final decision.
