Smith’s role as a substitute driver for Richard Petty Motorsports continues after he stepped in for Almirola last weekend in the Monster Energy Open. Smith finished fourth in the final stage of the race.
Almirola is expected to miss eight to 12 weeks as he recovers from a T5 compression fracture in his back. Almirola suffered the injury at Kansas Speedway in a major three-car crash.
Smith will be making his first start in a Cup points race this year. He currently drives for Ricky Benton Racing in the Camping World Truck Series.
Smith has 11 Cup starts at Charlotte Motor Speedway with a best finish of eighth in the 2011 Coke 600.
“To me, there are a lot of cool things about helping out again this weekend,” Smith said in a press release. “Being able to represent the Air Force on Memorial Day weekend and show appreciation to those who make the ultimate sacrifice is very special to me. I’m honored to race with Senior Airmen Mark Forester on the car and pay tribute to his sacrifice.
“As I said many times last weekend, to get to drive ‘The King’s’ 43 car means so much to me. The Coca-Cola 600 is one of my favorite races of the year, and Sunday is the coolest motorsports day. It will be a lot more fun being a part of such an iconic day than just being a spectator for all of the races.”
