Deftones bassist Chi Cheng was involved in a car accident Monday in Santa Clara, California and is now in a San Jose hospital, listed as in serious but stable condition.

Chi Cheng, 38, bassist for California rock band Deftones since its inception in the late 1980s, is in a coma after being involved in a serious car crash Monday, Nov. 3, in Santa Clara, per The Associated Press. Little is known about the circumstances of the accident or of the injuries sustained by Cheng.

The rock band’s singer, Chino Moreno, posted a message on the Deftones’ website Tuesday, Nov. 4, saying “our brother” Chi Cheng had been involved in a “terrible” car accident Monday night and that he is currently in a Northern California Hospital in serious but stale condition. Moreno said he and the rest of the band members as well as families were on their way to Cheng’s side.

The singer added his bandmate is “one of the strongest people” he knows and that he’s praying for him, asking fans to send a prayer as well.

The Deftones was formed in 1988, in Sacramento, Calif., when the four childhood friends, Chino Moreno, Chi Cheng, Stephen Carpenter (guitar) and Frank Delgado (keyboards and turntables), started playing in Carpenter’s garage. They released their first album “Adrenaline,” in 1994, via Madonna’s Maverick Records label.

“Elite,” off their 2000 album, “White Pony,” earned the band a Grammy Award for best metal performance.

The band had been working hard in the studio on their sixth album, “Eros,” which they planned to release next spring, via Warner Bros.

Chi Cheng has ventured on solo projects as well, releasing in 2000 “The Bamboo Parachute,” a CD comprised of his own spoken word poetry.
