Holderman received an injection in his right wrist Saturday, Tim Stebbins of MLB.com reports.
The right-hander departed his first rehab appearance with Triple-A Columbus on Thursday after aggravating his wrist injury, and he was set to resume throwing Monday after getting the injection. Holderman seems unlikely to rejoin the big-league bullpen during the final week of the regular season following the setback, but it's possible he's good to go next week for the start of the playoffs.
