query: sport redshirt 
supports: Redshirt , in United States college athletics , is a delay or suspension of an athlete 's participation in order to lengthen his period of eligibility . Typically , a student 's athletic eligibility in a given sport is four seasons , a number derived from the four years of academic classes that are normally required to obtain a bachelor 's degree at an American college or university . However , in a redshirt year , student athletes may attend classes at the college or university , practice with an athletic team , and dress for play but may not compete in games . Using this mechanism , a student athlete has up to five academic years to use the four years of eligibility , thus becoming a fifth - year senior . The origin of the term redshirt was likely from Warren Alfson of the University of Nebraska who , in 1937 , asked to practice but not play and wore a Nebraska redshirt without a number . The term is used as a verb , noun , and adjective . For example , a coach may choose to redshirt a player who is then referred to as a redshirt , and a redshirt freshman refers to an athlete in the first year of eligibility . A student athlete (sometimes written studentathlete) is a participant in an organized competitive sport sponsored by the educational institution in which he or she is enrolled. Student athletes must typically balance the roles of being a full-time student and a full-time athlete. Due to educational institutions being colleges, they offer athletic scholarships in various sports. Many student athletes are compensated with scholarships to attend these institutions but these scholarships are not mandatory to be considered a student athlete. In the United States, athletic scholarships are largely regulated by either the National Association of Intercollegiate Athletics (NAIA) or the National Collegiate Athletic Association (NCAA), which sets minimum standards for both the individuals awarded the scholarships (in terms of GPAs and standardized test scores) and for the institutions granting them (in terms of the form and value of the scholarships and the proportion of recipients who must ultimately earn degrees). The term "student-athlete" was coined in 1964 by Walter Byers, the first-ever executive director of the NCAA, to counter attempts to require universities to pay workers' compensation. The National Collegiate Athletic Association (NCAA) is a non-profit association which regulates athletes of 1,281 institutions, conferences, organizations, and individuals. It also organizes the athletic programs of many colleges and universities in the United States and Canada, and helps more than 450,000 college student-athletes who compete annually in college sports. The organization is headquartered in Indianapolis, Indiana. In 2014, the NCAA generated almost a billion dollars in revenue. 80 to 90% of this revenue was due to the Men's Division I Basketball Tournament. This revenue is then distributed back into various organizations and institutions across the United States. Walter Byers (March 13, 1922  May 26, 2015) was the first executive director of the National Collegiate Athletic Association. He served from 1951 to 1988. He also helped start the United States Basketball Writers Association in 1956. The NCAA Walter Byers Scholarship is named in his honor. An athletic scholarship is a form of scholarship to attend a college or university or a private high school awarded to an individual based predominantly on his or her ability to play in a sport. Athletic scholarships are common in the United States, but in many countries they are rare or non-existent.
