Koehler (shoulder) tossed a bullpen session Thursday and is expected to begin a rehab assignment at High-A Jupiter over the weekend, the Associated Press reports.

EDGE Analysis

Even before being diagnosed with right shoulder bursitis and hitting the disabled list two weeks earlier, Koehler was on the outs for a rotation spot, so he may stick around at Triple-A New Orleans once his rehab assignment concludes. The right-hander has compiled a 7.04 ERA and 1.64 WHIP in 38.1 innings this season.
