Cards Prepare for Canada Without Two: Louisville has opened practice in preparation for a Labor Day trip that includes three games against Canadian university teams. But sophomore point guard Andree McGee and freshman forward Derrick Character are not among the Cardinals practicing because of health issues. McGee is battling a case of dehydration that has landed him in the hospital. Coach Rick Pitino said doctors are running many tests to determine the best plan of action for now and during the season. Character slightly sprained his shoulder blocking a teammate’s shot in practice but should be ready soon. These injuries follow the loss of starting guard Brandon Jenkins to a broken leg and forward Brian Johnson to transfer. [8/29/06]
