Bichette, who is out of the lineup for Thursday's game against the Giants, was diagnosed with a fascia strain in his right calf, Keegan Matheson of MLB.com reports.
The 26-year-old suffered the injury during Wednesday's contest and is currently considered day-to-day. Bichette dealt with a strain in the same calf last month that resulted in a short stay on the injured list, though it's unclear if an IL move will be necessary this time around. The Blue Jays could add a player to the taxi squad in order to provide some potential depth at shortstop for the immediate future.
