Coulombe (elbow) will start his rehab assignment with Triple-A Norfolk on Wednesday according to pitching coach Drew French, Jake Rill of MLB.com reports.
Coulombe threw a live batting practice session Tuesday and is now ready for game action. Considering he's been out since mid-June after undergoing surgery to remove bone chips from his left elbow, it'll likely take a handful of rehab appearances before Coulombe is ready to return to the majors. He remains on track to be activated prior to the end of the regular season.
