Briscoe needs surgery and is out at least until next month’s race at Mid-Ohio.
“Carlos is a tremendous young driver with a great deal of talent,” Panther owner John Barnes said. “We’re excited that he was available to drive the National Guard Chevrolet today on such short notice, and I’m sure this will be a great learning experience for him. We’re obviously wishing Ryan a speedy recovery, but also very happy to make the most of this opportunity with Carlos today.”
Munoz had no other IndyCar races on his schedule this year following his breakout performance at Indy. He’d been trying to get into the August race at Sonoma, but with the focus on winning the Indy Lights championship has made long-term planning difficult.
Still, he hopes to be racing full-time in IndyCar next season and wants to use Sunday as a learning experience.
