St. Louis Cardinals first baseman Lance Berkmann has a torn meniscus in his right knee and is expected to miss six to eight weeks, general manager John Mozeliak announced during a press conference Monday.
Mozeliak said an MRI on Berkman's knee did not show a torn anterior cruciate ligament, but the 36-year-old will get a second opinion later in the week to make sure.
Berkman was hurt while stretching for a throw from shortstop Rafael Furcal on Justin Sellers' groundout in the second inning of Saturday night's 6-0 loss to the Los Angeles Dodgers.
Berkman, the NL comeback player of the year in 2011, is on the DL for the sixth time in his 14-year career. He had just returned to the lineup on May 13 after being sidelined for 21 games because of a strained left calf he aggravated while chasing a popup.
The Cardinals filled Berkman's roster spot by purchasing the contract of first baseman Matt Adams from Triple-A.
Berkman, a six-time All-Star, underwent surgery on his right knee in 2005 and on his left knee in 2010 while with the Houston Astros.
