The Xfinity Series field will feature several guest drivers at Nashville Superspeedway as several Cup regulars join the lineup.
The initial entry list for the Tennessee race, which features drivers fighting for 38 spots, has five full-time Cup drivers. Tyler Reddick headlines this list as he makes his first Xfinity start of the season while driving for Sam Hunt Racing.
The two-time Xfinity champion will be behind the wheel of the No. 26 Toyota GR Supra as he makes his third career start at Nashville in the second-tier series.
Ty Gibbs will make his return to the No. 19 Joe Gibbs Racing Toyota while John Hunter Nemechek will drive the No. 20 Joe Gibbs Racing Toyota. Both Cup regulars have made multiple Xfinity starts this season for JGR. Nemechek won the spring race at Las Vegas.
Neither Gibbs nor Nemechek has won at Nashville Superspeedway. Gibbs's best finish at the 1.33-mile track is fourth. Nemechek's best finish is sixth.
Ross Chastain and Noah Gragson are the other two Cup regulars making their return to Xfinity for the weekend at Nashville Superspeedway. Chastain, who won last season's Cup race at Nashville, will make his second start of the season for DGM Racing and his first Xfinity start at the track.
Gragson will make his second start of the season for Rette Jones Racing. He finished 10th at Charlotte Motor Speedway in his first foray behind the wheel of the No. 30 Ford Mustang. Now he will try to improve at a track where his best Xfinity finish is eighth.
"It's been a lot more fun in the Cup Series car, I know that," Gragson said about Nashville. "It's pretty wide and you can kind of go wherever.
"We weren't very good there in Xfinity, so I'm running double duty this weekend, Xfinity and Cup, just so I can try and get more laps and figure that place out."
While the Cup regulars will head to Xfinity for the Nashville weekend, three drivers from other series will move up to Cup for Sunday's Ally 400 (3:30 p.m. ET on NBC).
Truck Series regular Corey Heim will make his first start for 23XI Racing and the third Cup start of his career. He will drive the No. 50 Toyota Camry XSE.
Riley Herbst and AJ Allmendinger, who both compete full-time in Xfinity, will compete in Sunday's race. Herbst will make his return to Rick Ware Racing for only his second-ever Cup start at an intermediate track. Allmendinger, who won last season's Xfinity race at Nashville, will drive the No. 16 for Kaulig Racing on Saturday and Sunday.
