Martinez was injured during an offseason workout and will be operated on by renowned orthopedic surgeon Dr. James Andrews, the team said. A timeline for his return will be given after the surgery. Other players who have had the operation have missed six to eight weeks.
Martinez, 36, re-signed with the Tigers on a 4-year, $68 million contract in November. Martinez missed the entire 2012 season with a torn ACL in the same knee. He has played in all but 13 of the Tigers' games over the past two seasons. He had been a catcher earlier in his career but caught only five games after the knee injury.
Martinez finished second in MVP voting in 2014 after batting .335 with 32 home runs and 103 RBI. He led the American League with a .409 on-base percentage and had a major league-leading .974 OPS.
