Plouffe will undergo an evaluation on his sore ribs Monday, Rhett Bollinger of MLB.com reports.
Sidelined both Saturday and Sunday due to a rib concern, Plouffe will be examined thoroughly to determine whether a DL stint is needed. He's contended with the occasional injury this season, but only an intercostal strain has forced a stay on the disabled list through the first three months. If he requires more time on the pine, Miguel Sano and Eduardo Nunez would be in line for additional work at the hot corner.
