The Guardians announced Wednesday that Morris is dealing with a strain of the teres major muscle in his right shoulder and will be shut down for 4-to-6 weeks before being re-evaluated, Mandy Bell of MLB.com reports.
An MRI revealed the injury, which will keep Morris sidelined for the foreseeable future. The 25-year-old has yet to make his major-league debut since being drafted by Cleveland in 2018, but if he can get healthy, he'll likely get the chance to join the big club at some point in 2022. Morris made eight starts with Triple-A Columbus in 2021, producing a 2-2 record with a 1.72 ERA and 1.02 WHIP while striking out 52 in 36.2 innings.
