The term walk-on is used in sports, particularly American college athletics, to describe an athlete who becomes part of a team without being actively recruited beforehand or awarded an athletic scholarship. This results in the differentiation between "walk-on" players and "scholarship" players. Technically all Ivy League sports players are walk-ons; while they may have been actively recruited, league rules prohibit member schools from offering athletically-related financial aid. This also applies to football players in the Pioneer Football League, football players in the Patriot League whose college careers began before 2013, and all NCAA Division III athletes.
