Plouffe (intercostal strain) has been placed on the 15-day disabled list, retroactive to April 18, Cold Omaha's Brandon Warne reports.
Plouffe was diagnosed with a right intercostal strain shortly after being removed from Sunday's game against the Angels. Though initially considered day-to-day, he'll now be out until at least May 3. Jorge Polanco was called up from Triple-A Rochester for the corresponding transaction, but Eduardo Nunez figures to get most of the playing time at third base. Although he could play the hot corner in a pinch, Miguel Sano will remain in the outfield.
