How many games do you have to play in a season for that season to count against your four years of eligibility? Are the rules different for D1, 2 and 3?

Don't believe the rules are different except that beginning this year DIII level players are not allowed to redshirt for non medical reasons. Unless there is a medical issue involved, if you are in for one play during a season, that counts for your year of eligibility. In order to receive a non medical redshirt, the player cannot have participated during any game in the 56 game schedule.

Thanks. That's pretty harsh!
