I have been off work since june 15th.

I have been off work since june 15th with a severe partial acl tear. I am dealing with sedgwick, who handles my company's short term disability. I needed to have supporting evidence faxed by my doctor by 8/21. He was out of office that week and i took the first appt available after he returned which was 9/4. Sedgwick is now reconsidering my claim. My problem is that sedgwick told my employer i should have returned 8/14. My doctor has not yet released me to return to work as he wanted me to be fitted with an orthotic acl brace and attend physical therapy before returning. I received the brace 9/12. And have had three appts with physical therapy. My next appt with my doctor isnt until october 2nd. If my job fires me because i have exhausted my fmla leave can i receive unemployment after i fully recover from my injury?
