The Blue Jays placed Kirk on the 7-day injured list Sunday after he was diagnosed with a concussion.
After being struck in the catcher's mask by a foul tip in the third inning Saturday, Kirk was pulled from the contest and sent in for further evaluation. With tests confirming a concussion, he won't be eligible to return until at least Aug. 3, though fantasy managers shouldn't be surprised if Kirk needs more than a week to exit the concussion protocol. Ali Sanchez was called up from Triple-A Buffalo to provide the Blue Jays with another option behind the plate, but Tyler Heineman will handle starting duties in Kirk's absence.
