Shia LaBeouf's hand was "crushed" in the wreck that flipped his truck last weekend, and he still runs the risk of infection and other complications after a four-hour surgery, his lawyer said Friday.

The 22-year-old actor was injured in a late-night crash last Sunday in West Hollywood that authorities have since said was the fault of the other driver. The statement from lawyer Michael Norris said the driver may have been speeding and not paying attention.

LaBeouf was hospitalized and cited for drunken driving in the wreck, the impact of which flipped his truck after he tried to make a left turn around 3 a.m.

"Shia's left hand was crushed," read a statement released to The Associated Press on Friday from Michael Norris, a lawyer for the "Indiana Jones" actor. It added that LaBeouf's left arm was immobilized and that the production of the "Transformers" sequel has been modified to accommodate his recovery.

The actor has been recovering at a Los Angeles hospital since the surgery and "will need regular medical supervision until his doctors clear him to return to work," Norris' statement said. "We are hopeful that this return will be sooner rather than later."

LaBeouf and his attorneys have cooperated with police, the statement said, adding that "the Sheriff's Department has now released information that the other vehicle ran the red light while striking Shia's truck."

Norris also said independent investigators "received information that suggests that the other driver may have been traveling upwards of 50 miles per hour, and that said driver may not have been looking forward at the time of the accident."

Sheriff's officials have said they won't release the other driver's name until after a report is issued, which could take a few weeks while the official investigation is conducted. On Tuesday, sheriff's spokesman Steve Whitmore said LaBeouf was not at fault and that the other driver apparently ran a red light.

"We are very appreciative, again, of the patience that everyone has shown us, and of the many concerned citizens who have stepped forward to provide information regarding this collision," the statement continued, adding that anyone with information about the accident was urged to call Norris directly.

LaBeouf's credits include "Transformers," "Disturbia" and "Bobby." He can next be seen in the thriller "Eagle Eye," due next month.
