Brewers Reliever Koenig Out with Elbow Sprain

Manager Pat Murphy confirmed the injury is 'a big concern' but Koenig will attempt to rehab without surgery, with a projected return of two to four weeks. The left-hander, who posted a 2.67 ERA over 127 games with the Brewers, had been experiencing velocity issues this spring.

Shane Drohan was called up to replace Koenig and could make his MLB debut during the series at Fenway Park. The 27-year-old downplayed any significance of potentially facing the team that drafted him, focusing instead on the opportunity to pitch in the big leagues.
