This is in response to all the "Captain America died, r.i.p , etc" threads.
I was on wikipedia.org and I found this....

In Civil War: The Initiative, Ms. Marvel tells Spider-Woman (Jessica Drew) that Captain America is not dead but "...tucked away safe on the Raft..." with doctors working to save him.

Captain America's Death (section)
It's possible, although I wouldn't trust Wiki...especially about comics. I haven't read The Initiative yet.
