It's tennis time in Tennessee!

The Knoxville Challenger, a six-day professional tennis event hosted by Helen Ross McNabb Center, starts Tuesday and continues through Sunday, Nov. 13 at the Goodfriend Tennis Center.

The event is part of the USTA Pro Circuit. Aspiring pros will compete in a week-long schedule of matches for a $50,000 prize and national ranking points while raising money for Helen Ross McNabb Center.

Tickets are sold at the gate on a first come first serve basis for $10 per day.

Volunteer opportunities for the Challenger are still available at Volunteer East Tennessee.
