The hearing has been rescheduled for September 13, 2010.
Authorities say 23-year-old officer Matthew Sharkey was off-duty when he caused a crash that resulted in Trooper Matthew Sheeran being pinned against an abandoned vehicle. A preliminary hearing is scheduled for Monday.
Investigators say Sheeran and another trooper were trying to remove the vehicle from I-95 on February 20 when Sharkey ran over road flares and struck their vehicle.
Sharkey was placed on desk duty following the crash and later dismissed.
