Can I be laid off while on disability?

Question Details:

I'm short term disability in state of CA - been off work for 10 weeks. I work for a large company and was just notified by phone that my employment will be terminated upon my return next Monday (projected RTW date from my Dr.). But, my Dr. has not approved me yet to return to work. Can I extend my disability? I filed for MFLA thru employer for my original dates but the Dr. extended my absence and forgot to re-apply for FMLA. Although my letter from HR states that my FMLA leave continues through 12/15/09.
