In August 2008, Carterville unveiled a new outdoor athletic complex. The addition includes a football field with an artificial playing surface that sports a large "C" at midfield and also includes an all-weather track, enabling the school to host track meets for the first time in many years.
It has been a long-time tradition during Carterville football games that "The Cannon" is shot off after every Lions touchdown. "The Cannon" is an actual American Civil War cannon that is owned privately by a resident family of the town. The noise of the cannon was so loud that visiting fans were often taken aback at the boom, which could be heard throughout much of the town. "The Cannon" has become synonymous with the Carterville football tradition. Despite concerns of "The Cannon" being retired along with the old field, it has been taken out to the new complex and can still be heard following every Lions' score. The team often gives back to the community by bringing food to the homeless people that sleep behind the movie theatre.
Carterville has been a long-time member of the Black Diamond Conference. Other Black Diamond schools include Johnston City, Christopher, Zeigler-Royalton, Sesser-Valier, Elverado, Hamilton County, Fairfield, Carmi-White County, Trico, Vienna, as well as a few other schools for particular sports. In 2010, Carterville moved to the River to River Conference's Mississippi Division featuring larger schools such as DuQuoin, Anna-Jonesboro, Pinckneyville, Nashville, and Sparta. This switch has been made due to Carterville's rapid increase in enrollment, along with their football domination within the BDC.
