While originally called a "significant sprain" which would keep Kalish out for at least two weeks, it seems now as though the scope of the situation is much greater than that. Kalish hurt himself jamming his arm while attempting a diving catch in a recent Pawtucket Red Sox game.
The top prospect in Boston's system according to many, Kalish has been considered the heir apparent to J.D. Drew's spot in right field in recent years, and made his MLB debut with the team last year.
While this would be a fairly significant hit to Boston's depth, to say nothing of any long-lasting effect on Kalish's development, the Red Sox do have an obvious choice for a replacement in Josh Reddick. Not only has Reddick continued to put up big power numbers with a .556 slugging percentage, but suddenly he's posing an OBP threat too, having drawn nearly as many walks (10) as strikeouts (11) to start the season.
