Briscoe was injured in the first of two races at Toronto. He and Servia have been splitting time in the car since JR Hildebrand was released from the No. 4 after the Indianapolis 500.
"Oriol's part of our family so it's very seamless for the National Guard crew to get him back in the No. 4 car," Panther owner John Barnes said. "We didn't want to rush Briscoe back from surgery and obviously Oriol is a great IndyCar driver and does a phenomenal job working with our crew."
Servia's last start with Panther was at Iowa Speedway, where he finished seventh. He'll rejoin Panther Racing on Wednesday for a full-day test at Mid-Ohio in preparation for Sunday's race.
Servia has eight career starts at Mid-Ohio, with six top-10 finishes. He was a career-best fifth in 2008 while driving for KV Racing Technology.
"I'm very excited to be back in the National Guard car," Servia said. "Iowa was my last race, and while I love ovals, I'm really looking forward to getting back on a road course. Mid-Ohio is a very technical track and a (road course) specialist track, but I feel like everybody in our paddock is becoming a specialist because there are so many strong guys out there.
"We have a test day before the race that will be a big help for us fine-tuning the car, and especially for me to knock off a little rust. I'm looking forward to being competitive this weekend and there's no reason why we shouldn't be."
