Alejandro Kirk Injury: Being evaluated for concussion

Kirk is undergoing tests to determine if he has a concussion after he took a foul tip off his mask Saturday versus Detroit, Arden Zwelling of Sportsnet.ca reports.

Kirk initially remained behind the plate after being dinged by the foul tip, but he was pulled for a pinch hitter in the following frame. Should Kirk need to miss any games moving forward, Tyler Heineman figures to step in as Toronto's starting backstop.
