What's going on with Ike Diogu

When the Hornets signed him back in July I was extremely excited. I thought he could bring alot to this team, and even though I still think he can I am worried. He has not played a game this year, and I'm starting to believe he won't? What's going on with him is the ijnury that bad? If so is he even going to play this year? If he can't play what's next? We are still extremely thin when it comes to our frontcourt.
