Panther Racing's driver rotation will continue at Pocono, with Ryan Briscoe scheduled to take over from Oriol Servia as driver of the team's No. 4 car.
Briscoe's return, which was announced by team boss John Barnes on Twitter will mark his third weekend in the car following appearances at the Detroit double-header and Milwaukee.
Servia has raced the car at Texas and Iowa, with the team having already confirmed that it intends to continue evaluating different drivers over the remainder of the season before committing to a full-time signing for 2014. The seat was made available by the departure of JR Hildebrand after the Indy 500.
Meanwhile, Panther has also made changes on the technical front, with the team confirming during the Iowa weekend that engineer David Cripps has left. Tino Belli, who was hired during the off-season as technical director of the joint Panther/DRR program, will assume Cripps' responsibilities.
