(1) Service Exception, (2) Pregnancy (obviously does not apply here), (3) Athletics Activity Exception (Pan Am Games, World Championships, Olympics, etc.), (4) Five-Year Rule Waiver (consists of; Circumstances Beyond Control, and Circumstances Within Control, with a list of both for getting a 6th Year) NOTE: The Five-Year Rule Waiver is what would be applied for to get Anthony a 6th Year.
Then there's the Hardship Waiver, often called a Medical Redshirt. Anthony already had a Redshirt Year, so this is not an option.
Hope that helps...paraphrased a good bit.
Interesting. Gravina at Rutgers had a redshirt year, so I'm guessing he also got his extra year under the five-year rule waiver rule rather than the "medical redshirt" rule. This is some obtuse stuff.
