Dodgers shortstop Hanley Ramirez is scheduled to undergo surgery Friday on his injured right thumb and is expected to be sidelined for eight weeks.
The Dodgers said Thursday that an MRI indicated that a ligament in Ramirez's thumb was torn.
Ramirez suffered the injury Tuesday night while playing for the Dominican Republic in its victory over Puerto Rico in the World Baseball Classic championship game in San Francisco.
Ramirez was at third base when he suffered the injury. The Dodgers moved him to shortstop, his original position, after obtaining him from the Miami Marlins on July 25.
Dr. Steve Shin, a sports-medicine hand specialist, is scheduled to perform the surgery in Los Angeles.
The Dodgers were in Tucson, Ariz., on Thursday for a spring training game against the Chicago Cubs.
