Swanson (forearm) was sent to the Blue Jays' Florida Complex League affiliate Friday to begin a rehab assignment.
Swanson had been slated to start a rehab assignment in late April before encountering a setback. However, an MRI on his injured right forearm came back negative at the beginning of the month and he's ready to give it another shot. Swanson is on the 60-day injured list and won't be eligible for activation until late May, even if his rehab stint goes smoothly.
