The San Diego Padres could be without Mike Clevinger for the entirety of their playoff run.

The right-hander continues to deal with an elbow posterior impingement.

Clevinger, 29, threw a 23-pitch bullpen session on Tuesday, but the session "didn't resolve questions about his short- and long-term arm health," according to a report.

San Diego acquired Clevinger from the Cleveland Indians before the Aug. 31 trade deadline.
