NASCAR Cup Series owner joins Jimmie Johnson on Truck Series entry list for San Diego

Trackhouse Racing owner Justin Marks has joined Jimmie Johnson on the NASCAR Truck Series entry list for San Diego.

All three national NASCAR series are set to be in action at the Naval Base Coronado over the weekend of June 19-21, as the sport celebrates the 250th anniversary of the United States and the Navy.

With full-time Cup Series drivers not allowed to drop down to the O'Reilly or Truck Series that weekend, it has presented opportunities for others. Jimmie Johnson is set to drive for Tricon Garage at the event, and now Marks has been confirmed to pilot one of Spire Motorsports' trucks.

Marks' main focus these days is on his ownership role at Trackhouse, but he also has 81 outings under his belt across the Cup, O'Reilly and Truck Series. His last NASCAR outing came in the O'Reilly Series race at Chicago in 2023, while the last Truck Series race he competed in was at Michigan in 2022.

Marks honored ahead of unique NASCAR opportunity

"It's a unique opportunity to drive in the inaugural Truck Series race at San Diego Naval Base," Marks said in an official Spire Motorsports statement.

"I'll enjoy getting behind the wheel every once in a while, and I'm thankful to do it with Spire's help and with a longtime partner like Jockey.

"They are celebrating their 150th anniversary and are very supportive of our military which makes the endeavor even more special.

"There is a lot of excitement surrounding the upcoming race weekend and it's an honor to be a part of it."
