Alejandro Kirk Injury: Tracking toward return Sunday

Kirk (concussion) is tentatively on track to play a rehab game with Triple-A Buffalo on Saturday before being activated from the 7-day injured list Sunday, Keegan Matheson of MLB.com reports.

Kirk was diagnosed with a concussion after taking a foul tip off the mask in a game this past weekend. However, he has recovered well since then, and as long as he keeps progressing well, he'll be in line for a minimum-length absence. Tyler Heineman has been handling the primary catching duties for the Blue Jays since Kirk went down.
