Plouffe was diagnosed with a cracked rib and placed on the 15-day disabled list Monday, Phil Miller of the Minneapolis Star Tribune reports.
The Twins made Plouffe a late scratch Sunday against the Rangers due to what was labeled a case of sore ribs, but a follow-up examination revealed the corner infielder was dealing with something a little more severe. There's been no timetable given yet for Plouffe's return, but the impending All-Star break at least means he won't miss as many actual games as a normal 15-day DL placement would entail. While Plouffe remains out, Eduardo Nunez could end up seeing some more time at third base, opening up more action at shortstop for Eduardo Escobar or Danny Santana.
