Barber added that the squad is still unsure what led to the crash, with data from the wrecked car currently unavailable.
"Not at this time," he said. "We have to wait for Tim to be cleared to see the car and get the data out of it. So right now we're unclear."
With its sole car out of the race, the team has already began packing up for the trek back to the US.
"The important part of it is that Tim is okay, that's what we're really concerned about. But being here and coming all this way and all the work that went into it, of course we're disappointed," Barber said.
Update: Porsche has issued another statement, revealing that Pappas suffered fractures on his right arm and pelvis. He will stay in clinic for further treatment.
