Hall injured his right shoulder while playing first base during yesterday's loss to the Texas Rangers. He was hurt when he dove for a groundball, and is expected to miss significant time with what is thought to be a torn labrum.
Hall underwent an M-R-I exam today and the White Sox are working to schedule an appointment for him with a Los Angeles Angels orthopedist for further testing.
General manager Kenny Williams sayas the club would fill the position internally, with either Gustavo Molina or Wiki Gonzalez.
Manager Ozzie Guillen says the team will poll the pitching staff about the comfort level with both.
