Haniger (back) was placed on the 60-day injured list Sunday, Shannon Drayer of 710 ESPN Seattle reports.
GM Jerry Dipoto said Wednesday he wasn't sure of Haniger's status for summer camp, but his removal from the 40-man roster makes clear he needs additional time before retaking the field. The 29-year-old ruptured a testicle last summer and required additional surgeries in early 2020 for that issue, and he also underwent a microdisectomy in February to fix a vertebrae in his lower back. Jake Fraley is expected to see time in left field for Seattle, and it remains unclear if Haniger will be able to participate in the shortened 2020 season.
