Acevedo (back) threw a bullpen session Tuesday and is expected to begin a rehab assignment with Triple-A Las Vegas before the end of the week, the Associated Press reports.
The veteran reliever went on the injured list with a lower-back strain back last Wednesday, so it's certainly a positive that he's already able to throw without issue. Given his relief role and the fact he's been sidelined for a short period, Acevedo is a likely candidate for a brief rehab assignment.
