Plouffe (ribs) is set to begin his rehab assignment with Triple-A Rochester on Monday after going through a good batting practice Thursday, Rhett Bollinger of MLB.com reports.
Plouffe has been out since early July as he's been recovering from a cracked rib. He seems to be progressing nicely, and after competing in a few rehab games with Rochester, Plouffe could be ready to rejoin the big league club by next weekend.
