HOMESTEAD, Fla. -- NASCAR tentatively plans to add Eldora Speedway in Ohio and Greenville-Pickens Speedway in South Carolina to the Truck Series schedule in 2013, NASCAR officials confirmed on Friday.

The series is looking to move to Myrtle Beach Speedway in South Carolina in 2014.

NASCAR executive Steve O'Donnell said on Saturday that experts from the University of Nebraska that developed the SAFER barriers used at all tracks in the top three series are scheduled to visit Eldora Speedway after Thanksgiving.

O'Donnell said that if plans to design a barrier that can be anchored to dirt is financially feasible for track owner Tony Stewart, the series will schedule a race at the half-mile track next season. It will be the first time NASCAR has scheduled a race on dirt since 1970.

O'Donnell said Nebraska officials already have visited Greenville-Pickens Speedway, a half-mile paved track in South Carolina, and plans are moving forward to add barriers.

O'Donnell also said NASCAR is considering heat races in the Truck Series, another way for the sport to get back to its roots.

O'Donnell said the Truck schedule should be released in the next week or two.
