Four Knoxville teams are in action today. The Girls Tennis squad hosts Chariton in their season opener at the Joel Tonda Tennis Courts. The boys and girls track and field squads hope today is their first outdoor meet of the season. Both meets last week were called off and Tuesday’s meet at P-C-M was also cancelled. The boys travel to Indianola while the girls head to Centerville. The boys soccer squad ends its busy opening week with a trip to Albia. The Panthers are one-and-one on the season after dropping their conference opener Tuesday at Grinnell.
