Jack Perkins Injury: No timetable for return

Perkins (shoulder) received a subacromial injection Monday and is without a timetable for a return, Martin Gallegos of MLB.com reports.

Perkins was placed on the 15-day injured list Friday due to a strained right shoulder, and the club is still uncertain as to how much time he'll miss. Whether he's able to pitch again this season should become more apparent when/if he's cleared to begin a throwing program. Osvaldo Bido is expected to replace Perkins in the rotation in Tuesday's game against the Tigers.
