The NCAA Division I Council officially adopted a resolution to allow all Division I Winter sports athletes an additional year of eligibility, regardless if they compete this season or not.  If implemented in the same fashion as the waivers granted to 2020 spring and fall athletes, those seniors that return next year won't count against their school's scholarship limits in 2021-2022.  The additional year and scholarship are not guaranteed.  They are up to the school's choice, and likely dictated by budget.  If implemented the same as the rule in Division II, it appears that the relaxation of the scholarship limits does not apply to a senior that transfers schools for supplemental year of eligibility in 2021-2022.
