Pirates reliever Rob Scahill will start a minor league rehab assignment on Thursday, manager Clint Hurdle said, per MLB.com.
Scahill has been on the disabled list since June with forearm tightness.
Scahill is scheduled to pitch two innings or 35 pitches for the Pirates' Gulf Coast League team. After that, he'll return to Pittsburgh to throw for the coaching staff on Monday, then make a second rehab appearance next week, pitching three innings or 50 pitches at Double-A Altoona.
