take a look few paragraphs bellow, the news aren't really bad:
The good news is that Houston has been in close contact with McDyess, he said, and is more certain than ever the power forward will play this season. McDyess had surgery on April 21 on his left patella - his third knee surgery in 18 months.
"It doesn't matter if it's October, there's no doubt he will be back," said Houston, appearing at the Knicks summer kids camp at Basketball City. ". . . My sense is he's ready to do more than the team is willing to allow him right now. He's got to be patient. You don't want to rush. He wants to do a little bit more."
