ESPN’s Jesse Rogers reports Justin Steele (elbow) has been shut down from throwing following a setback.

Cubs manager Craig Counsell told reporters Steele will be sidelined until after the All-Star break in July following the setback. The 30-year-old left-hander has been working his way back from last year’s Tommy John surgery and recently progressed to facing hitters in live batting practice sessions. He underwent imaging that didn’t reveal any structural damage, but has been diagnosed with a flexor strain, after experiencing discomfort while throwing over the weekend.
