Bednar (back) will require a rehab assignment prior to returning from the injured list, Justice delos Santos of MLB.com reports.

EDGE Analysis

Bednar threw live batting practice Saturday and will ultimately need to spend some time in the minors before he's activated by the Pirates. The team hasn't yet determined the specifics of his rehab assignment, but it wouldn't be surprising to see the right-hander remain sidelined until at least late next week.
