Manny Ramirez is going on the disabled list for the first time since being traded to the Dodgers.

According to's Ken Gurnick, the veteran outfielder aggravated a strain in his left calf and will need at least two weeks to heal.

Ramirez, who initially suffered the injury during the first week of the season, underwent an MRI on Friday showing the extent of the damage. The Dodgers are optimistic he will be ready to return once eligible.

The 37-year-old had been red-hot at the plate to start the 2010 season, hitting .415 with two homers and 12 RBIs in 41 at-bats. With nine walks and only three strikeouts so far, Ramirez ranked sixth in the league with a 1.159 OPS after 13 games.

The Dodgers have called up outfielder Xavier Paul from Triple-A Albuquerque to take Ramirez's spot on the roster, although it is unclear whether Paul will see much playing time with veteran reserves Garret Anderson and Reed Johnson available off the bench.
