The Knoxville Raceway will have a rare Tuesday night racing event as the Harris Clash Series will stage a late model and sport mods show tonight. Earlier in the month Eric Dailey picked up the Harris Clash modified win. Ray Guss Jr. was the last model winner last year, and Jared Timmerman was the 2010 sport mod winner. Hot laps begin at 6:30 with racing at 7:15.
