ROSSBURG, Ohio – NASCAR Gander Outdoors Truck Series competitor Spencer Boyd will sit out Thursday’s Eldora Dirt Derby at Eldora Speedway because of a back injury.

Landon Huffman will drive the No. 20 Young’s Motorsports Chevrolet Silverado in the Eldora Dirt Derby while Boyd recovers. It will be Huffman’s fourth series start.

Boyd confirmed in a tweet Tuesday that the injury happened prior to the race last week at Pocono Raceway in Long Pond, Pa. He said he raced at Pocono against his doctor’s recommendations.

“For the last week I’ve had back pain that I’ve been fighting through,” Boyd said. “I went against my doctor’s advice and raced at Pocono. I’ll be taking his advice this time and sitting out Eldora and perhaps more races to heal properly.”
