I had no idea he had a hip injury. I thought it was a shoulder (labrum) and neck injury that had been dogging him for the past couple of years. Either way, it doesn't matter if Ozzie knew about it or not. Ed was a UFA and Ozzie is not obligated to announce injuries of potential ex-players. It is Houston's responsibility to make sure there are no injuries that would cause them concern, and it's Ed's responsibility to be open and honest about any injuries that he might have.
