A friend with a connection at a certain hospital in NY told me Amare had surgery about 2 weeks ago. I wasn't able to find out what the procedure was, but was told it was likely not on his back.
I then found out from another person who was in contact with Knicks management that Amare did have some type of injury and a surgery.
You can take that for what it's worth... I'm a Nets fan but figured you guys would be interested (even though you all probably wish the guy was playing in Israel instead of NY this season). Amazing that this hasn't been leaked or reported elsewhere.
