The rivalry between Nebraska and Colorado, one-sided for much of its history, gained traction with Colorado's resurgence in the 1990s. The teams have met 71 times, with the series dating back to 1898, a 23–10 Nebraska win. The Cornhuskers lead the series 49–20–2. The rivalry began when Colorado joined the Big Eight in 1947; they played in the same conference as Nebraska until 2010. A bison head named Mr. Chip was presented to the winning team throughout the 1950s, but this exchange ended when Colorado misplaced the trophy in 1961. The teams have not played annually since both programs exited the Big 12 in 2011, but future non-conference games are planned for 2023 and 2024.
