"We're excited to be able to provide this opportunity for Darrell in Talladega," said JGR team president J.D. Gibbs. "He has been doing a great job in the Truck Series with his KBM team and we want to make sure he continues to gain experience in our Nationwide Series cars, as well."
Wallace, who is eighth in Truck Series points after two races this season, made his only Talladega start in a KBM truck last fall and was poised for a strong finish before being caught up in a multi-vehicle wreck on the final lap.
"It's good to be back behind the wheel of a Toyota Camry for Joe Gibbs Racing in the Nationwide Series," Wallace said. "I'm excited to work with Kevin Kidd and all the guys on this Nationwide Series team. I know they have a good Toyota Camry and Matt (Kenseth) has been running it all season long and posted good finishes.
"Hopefully, we can go out there, stay out of harm's way and add to that by posting a good, strong finish at Talladega for the No. 20 ToyotaCare team."
