Gordon will hand driving duties of his team's #7 car to Gilliland as he is set to compete in an off-road truck racing event in Nevada.
Robby Gordon Motorsports will be Gilliland's third team in as many races, following his outing in a TRG Motorsports Chevrolet at Bristol and in a Wood Brothers Ford at Atlanta.
Gordon is also set to compete in Wednesday's 'Prelude to the Dream' charity event, hosted by two-time Cup champion Tony Stewart at Eldora Speedway in Ohio.
"We had a great run in the Cup car on Sunday," said Gordon about last weekend's race at Atlanta. "I'm excited for Eldora and Primm later this week, and I'm also happy to have David Gilliland driving the #7 at Richmond this weekend."
Following Sunday's race, Gilliland is expected to swap between TRG Motorsports and Joe Gibbs Racing for the remainder of the season.
