DeMario had the injury from his senior year at NC State. The team thought it was healed but it turns out it wasn't fully healed. He will have surgery on it to have it repaired. He didn't look to see much playing time this year anyway because he has Sedrick Ellis, Hollis Thomas, and Bryan Young all in front of him.
The hamstring injuries to Henderson and Porter were minor and they are day to day. The whole thing just sounded a lot worse than what it actually was.
