Morton was placed on the 10-day disabled list Sunday with a strained lat muscle, Brian McTaggart of MLB.com reports.
The news seemingly comes out of nowhere, as Morton reported no issues after coming out of his most recent start Wednesday against the Tigers, when he gave up two runs over seven innings. The Tigers haven't issued a timetable for his return yet, but that could be solidified once Morton is reevaluated in subsequent days. Mike Fiers, who had recently been moved to the bullpen in favor of Brad Peacock, will likely reclaim a spot in the rotation with Morton's injury creating a vacancy.
