Best wishes to him, the band, and his family. Hopefully he comes out of it. Source: http://www.roadrunnerrecords.com/blabbermouth.net/news.aspx?mode=Article&newsitemID=108280
This is horrible news. I hope he recovers quickly. Personally, though I think the Deftones are a bit overrated, Cheng is a brilliant bassist.
The deftones are my absolute favorite band...I actually couldn't believe it when I heard Chi was involved in a car accident. My prayers go out to him.
