A kickball tournament in Knoxville last week raised more than $100,000 for children’s cancer research. The Tony Stewart Kick-It Cup was held on Friday at Young’s Park. A number of sprint car drivers participated, and an auction was also held. An anonymous donor purchased a racing helmet decorated by a child for $10,000. Tony Stewart himself, recovering from his broken leg, phoned in a bid of $4000 for a helmet signed by Jeff Burton. The event raised money for Kick-It for Cancer, a charity that’s part of the Jeff Gordon Children’s Foundation. Speaking in Knoxville last week, Gordon said he was grateful for the sprint car community’s support of the event.
