Schultz (knee) threw a bullpen session Wednesday, James Fegan of SoxMachine.com reports.
Manager Will Venable said that Schultz will throw at least one more bullpen session before the White Sox potentially plot out a rehab assignment for the rookie left-hander, who has been on the shelf since May 26 due to right knee patellar tendinitis. Prior to landing on the injured list, Schultz went 2-4 with a 5.82 ERA, 1.34 WHIP and 33:22 K:BB across 38.2 innings.
