 Centennial is part of what is believed to be the sixth oldest high school football rivalry, and the oldest west of the Mississippi River, with their annual game against cross-town rival Central High School.The schools first played in 1892 and played fairly regularly thereafter until 1907 when a brawl at that year's game and then JROTC training during World War I put a temporary halt to the series.Since resumption of the series in 1921 the teams have met every year.
