Doctors are “optimistic” that Deftones' bassist Chi Cheng will make a full recovery following a car crash in California.

Cheng suffered severe injuries after the vehicle he was in came off the road in the Santa Clara area of San Jose last week.

A message on the band's website said the bassist, who was in a coma when taken to hospital, had passed the crucial 72-hour mark.

“Chi was able to hear and respond to his father's request to move his lower lip,” the band wrote.

“His father also administered a tendon reflex test, of which both legs responded with movement.

“Doctors continue to remain optimistic, and the energy at the hospital remains very positive.”

The band also said that Chi's family would like to thank fans for their “love and support”.

The Grammy Award winning band, who formed 20 years ago, have been recording their sixth studio album, 'Eros', which is due out next April.
