Dylan Cease’s first season with the Toronto Blue Jays may be over after he undergoes an MRI related to a shoulder injury, according to reports. The teams’ medical update suggests the right-shoulder issue could prevent him from starting again this season, though the outcome of the imaging is not described in detail in the coverage.

The news arrives as Toronto deals with multiple pitching injuries and faces pressure in the postseason race. Several outlets link Cease’s situation to the broader strain on the team’s rotation during a critical stretch. Across the reporting, the emphasis differs: one source focuses on the possibility that the season is effectively finished following the MRI, while another highlights Cease’s recent production—leading the American League in strikeouts and ranking near the top in ERA—alongside concerns that his injury could limit his availability.
