The AP reports: The Houston Rockets, buzzing about the arrival of Ron Artest, already have injury concerns with Tracy McGrady. Houston’s leading scorer said Monday that his left shoulder is arthritic and will require surgery after this season. He also said his left knee is healing slower than expected from surgery in the spring. McGrady sprained his shoulder against Sacramento on March 24, and wore padding to protect it for the rest of the season. He had surgery in May to clear loose tissue in his shoulder and knee. He said his knee is “probably 75-80 percent” healthy and will take another two months to fully heal.
