After getting the results of an MRI exam, the Red Sox decided to place Mike Lowell on the 15-day disabled list with a sprained left thumb.

Lowell injured the thumb Wednesday night diving for a ball hit by Detroit's Ivan Rodriguez in the first inning.

Infielder Jed Lowrie was brought up from Pawtucket to replace Lowell on the roster.
