Pop returned to Toronto on Monday for further evaluation after feeling renewed discomfort in his right hamstring during his most recent rehab appearance Friday with Single-A Dunedin, Scott Mitchell of TSN.ca reports.
Coming out of the weekend, Pop's return from the 15-day injured list appeared imminent, but he's now hit a bump in the road. Even if Pop's re-evaluation reveals nothing overly concerning, he's still likely to put his rehab program on pause for at least a few days.
