Church (shoulder) will begin a rehab assignment with High-A Hickory on Sunday, Jeff Wilson of RangersToday.com reports.
A member of the Rangers' 40-man roster, Church has yet to make his MLB debut and has been out since mid-April with a right lat strain. He remains on Triple-A Round Rock's 60-day injured list and will likely require multiple rehab appearances in the lower levels of the minors before he rejoins the Rangers' top affiliate.
