http://www.athleticscholarships.net/2012/07/17/how-get-medical-redshirt.htmCan you tell me where you're seeing this, that you have to miss 2 seasons due to injury?
I've always known the medical redshirt requirements to be that you can't play more than [30%] of the games in a season, and can't play in the second half of the season.
I think that's the correct percentage of games.
Is football different from other sports? Naz just got a medical redshirt in basketball for last season. He didn't miss 2 seasons.
Maybe this has changed or like I said, is different for football.
Short version:
A "regular" redshirt must be 100% no playing during a season.
A "medical" redshirt can play 30% of a season and then get injured. This is used to play a 5th season after losing at least 70% of a previous season to injury.
BUT -- the big deal is the 6th year of eligibility. For this, you must show that 70% or more of 2 separate seasons were lost due to injury.
Of course, you can still apply. And there are exceptions (somewhat rare). But those are the rules.
IIRC Case Keenum was able to prove an injury for his freshman redshirt year, thus having 2 seasons lost due to injury.
