A medical redshirt is a student who misses an entire year of competition due to injury and is granted an extension of his or her athletic eligibility to replace the lost season.
In men's college basketball, a student who participates in less than 30 percent of his team's games may apply for medical redshirt status.
The term is derived from redshirt, the practice of sitting out a year by choice, usually to avoid wasting a year's eligibility on a season that would otherwise be spent on the bench. Redshirting is far more common in football than in basketball.
Syracuse guard Eric Devendorf tore the anterior cruciate ligament in his left knee during a game last December, and missed the remainder of the season. Because he had played in just 10 of Syracuse's 32 games, the Big East determined that Devendorf was eligible to apply for a medical redshirt. That request was granted in September, and as a result Devendorf is now classified as a junior athletically
for the 2008-09 season.
