DETROIT -- Victor Martinez had knee surgery and will need a second operation, another indication he is likely to miss the entire 2012 season.
The Detroit Tigers star had microfracture surgery Friday to repair the medial and lateral meniscus in his left knee. He is projected to have anterior cruciate ligament reconstruction surgery on the same knee in six to eight weeks.
The team announced Monday that Martinez was expected to be out for the year.
When the Tigers revealed two weeks ago that Martinez tore his left ACL during offseason conditioning, they said the designated hitter would "most likely be lost" for the 2012 season.
Detroit signed Prince Fielder last week to make up for the loss of Martinez, investing $214 million over nine years in the free agent slugger.
Martinez hit .330 with 103 RBIs in 2011, helping the Tigers win the division in his first season with them. He signed a $50 million, four-year contract before last season.
Fielder matched his career-high .299 batting average last year -- his seventh with the Milwaukee Brewers -- with 38 home runs and 120 RBIs. He finished among the top five in AL MVP voting for the third time.
Detroit won the AL Central by 15 games last year, advanced past the New York Yankees in the playoffs and was eliminated by Texas in Game 6 of the AL Championship Series.
