The registration deadline for youth spring soccer at the Knoxville Recreation Center is this Friday, April 4. Recreation Director Brandon Nemmers says the program is for kids from 3 years old through first grade. He says the games will be at the Rec Center soccer fields on Tuesdays and Saturdays. He says this is the Rec Center’s largest youth sport, and they pair the 3 through 5 year olds for the preschool group, and kindergarteners and first graders are another group.
