In 2011 Greyhound football adopted black (rather than crimson) as the primary dark jersey color, and most other UIndy teams soon followed suit.
Following a winless 1931 campaign with just 15 players, Indiana Central dropped football and did not resume the sport until 1946, amid the post-World War II boom in college enrollments.
In 1947, the Greyhounds became charter members of the Hoosier College Conference,[4] and subsequently joined the National Association for Intercollegiate Athletics (NAIA).
They remained in the Hoosier conference until 1970, winning championships in 1947, 1953, 1954, 1955, and 1960, but never qualified for playoffs under the NAIA (which did not hold its first postseason football game until 1956).
Indianapolis posted 10 winning records in 22 seasons of MIFC-GLIAC play, including an 8–2 mark in 1998, good enough for a second-place finish, but never qualified for the postseason.
Indianapolis began playing football in the GLVC in 2012, when the conference (in its 35th year of competition) finally had enough football-playing members to sponsor the sport.
From 1924 to 1988, every Greyhound football schedule included Franklin College, located twenty miles south of the Indianapolis campus.
After the Bulldogs won 10 of the first 11 meetings, the crosstown rivalry became quite heated, with neither team winning more than two consecutive games during the years 1977–93.
When St. Joseph's closed at the end of the 2016–17 academic year, Indianapolis led the series 30–10–1, on the strength of 17 consecutive victories from 1995 onward.
Initially Hillsdale dominated the rivalry, but Indianapolis has turned the tables by winning nine of the last ten meetings, and currently leads the series 20–16.
