After a six/nothing thrashing over Oskaloosa, the Knoxville Boys Soccer Squad will head to Pella and take on their cross county rivals in the class 2A sub state semi-finals tonight. Coach Jon Smith says Pella and Knoxville is always an intense match because usually a lot is on the line. The match is scheduled to kick off tonight at six-30 with the winner advancing to the Sub State final to play either Norwalk or Centerville.
