Dylan Cease undergoes MRI on right shoulder, scratched from next Blue Jays start

Dylan Cease underwent an MRI on his right shoulder and has been scratched from his next scheduled start with the Toronto Blue Jays, MLB.com's Shanthi Sepe-Chepuru reported.

What happened

Cease, Toronto's right-handed starter, had imaging done on his right shoulder and will not take his next turn in the rotation. The nature and severity of what prompted the MRI have not been reported, and no diagnosis, timetable, or roster move has been announced in connection with the injury.

The scratch lands at a complicated moment for a Blue Jays rotation that has been reshuffled more than once in recent weeks. Four days ago, per a previous Posterior Wire item, Toronto had already reorganized its starting order — moving Cease to a Friday slot, with Soriano on Saturday and an Arrighetti/bullpen arrangement pushed to Sunday. That plan is now in flux again.

Why it matters

The Blue Jays are 76-79 and have been eliminated from the AL East division race, sitting 18.5 games back in fourth place. The rotation's health, at this stage of the season, is less about October positioning and more about organizational accounting: who is available, who is being protected, and what the final weeks reveal about the club's longer-term picture.

Cease is the kind of arm that makes those questions matter. A right shoulder MRI — even one whose results remain unreported — is the sort of development a front office watches closely regardless of where the team sits in the standings. The shoulder is the joint that tends to deliver its news slowly and without much fanfare, which is why the desk will not speculate on what the imaging may or may not show. What is known is that he will not pitch in his next scheduled turn.

The rotation's depth has been tested repeatedly this month. A week removed from Jameson Taillon announcing he would not return in 2026 due to elbow inflammation — with broader UCL concerns noted given his two prior Tommy John surgeries — Toronto is now managing another absence at the front of its staff. Taillon's situation involved a meeting with Dr. Keith Meister, per earlier reporting; no such detail has been attached to Cease's MRI.

Is Trey Yesavage now in line for Cease's spot?

Possibly, though nothing has been formally announced. Per multiple Posterior Wire items over the past several days, Trey Yesavage has been working his way back from a meniscus injury and is expected to come off the injured list to start Monday against the Baltimore Orioles. MLB.com lists Yesavage as Toronto's probable pitcher for that Monday game at Oriole Park at Camden Yards. His return had already been in motion before Cease's scratch — he threw a side session Friday and was on track for the Monday start — so the timing is coincidental rather than causal, at least as reported.

What Cease's absence does is remove a scheduled arm from later in the week, creating a gap that the club will need to fill through some combination of rotation adjustment, bullpen deployment, or a call from the expanded September roster. Under general league rules, September rosters expand to 28 players, which gives clubs additional flexibility to carry arms without the same constraints that apply earlier in the year. How Toronto uses that flexibility in response to this scratch has not been reported.

Where the club stands

Toronto is 76-79 (.490), fourth in the AL East, and eliminated from the division race. In the Wild Card picture, the Blue Jays rank fifth, 3.0 relative to the cut line, and have dropped two straight heading into Sunday's contest at Globe Life Field against the Texas Rangers, where Spencer Miles is listed as Toronto's probable against Jacob deGrom.

From there, the club travels to Baltimore for back-to-back games Monday and Tuesday. Yesavage is projected for Monday, with Max Scherzer slotted for Tuesday against an Orioles probable that remains to be determined. That is three games in three cities across three days — the kind of stretch that makes rotation depth feel less like a luxury and more like a logistical necessity. With Cease scratched and Taillon already done for the year, Toronto is leaning on Scherzer, Yesavage's return, and whatever the bullpen and depth options can provide.

What we don't know yet

The MRI results have not been reported. No diagnosis has been attached to Cease's right shoulder. No timetable for a potential return has been mentioned. No roster move — IL placement, replacement starter, or otherwise — has been announced in connection with the scratch. Whether this is a precautionary measure or something more significant is entirely unknown based on available reporting.

The club has not issued a formal statement beyond what Sepe-Chepuru reported for MLB.com. Until imaging results are disclosed or a roster transaction is announced, the situation remains open.

What to watch

The first thing to monitor is any roster move the Blue Jays make in the coming days. A pitcher scratched with a shoulder MRI pending is a candidate for the 15-day injured list — that is general league mechanics, not a reported fact about Cease — and any such transaction would tell the story more clearly than the scratch itself.

Watch also for an updated rotation alignment. With Cease out of his slot and Yesavage returning Monday, Toronto's pitching schedule for the final stretch of the regular season will need to be reconfigured. Whether that means a bullpen game, a stretched-out reliever, or a depth starter getting a turn has not been reported.

Finally, keep an eye on any update from the club or from Sepe-Chepuru at MLB.com, who broke the initial report. The MRI has been done; what it showed is the next piece of this story.
