That's a little misleading... you can get a Medical Redshirt to have your games not count against your 4 years of eligibility, but you still have to appeal to the NCAA and have them extend the 5 year part of that rule (you have 5 years to play 4). It's a two part thing and this case you'd need both extensions. It would be interesting to see if the NCAA would grant an 8th year to play 4 in this case.
