"At DI schools, the player will only have 3 years of eligibility (depending on their collegiate gpa, they may be granted a 4th year of eligibility if they maintain a 2.7 cumulative GPA or higher) - in both situations, if they choose to play their 4 year of eligibility they will be playing as 5th year Seniors."
So at least as I interpret it, there is at least a decent chance he could come back?
