Koenig, who has been an important pitcher for the Brewers with a 2.67 ERA over 127 games in his first two seasons, will attempt to rehab the injury and avoid surgery. His velocity has decreased this season, with his sinker averaging 93.5 mph, and he felt more discomfort in his last outing.
Shane Drohan was called up from Class AAA to replace Koenig and may make his MLB debut against the Red Sox, the team that traded him this offseason. The 27-year-old downplayed the significance, stating 'it's just pitching in the big leagues that has always been the goal.'
