Per Rob Bradford:
According to a major league source, Red Sox outfielder Ryan Kalish is likely to undergo surgery for an unspecified ailment, forcing the outfielder to miss spring training. The injury is not to Kalish’s neck, which was one of the issues he dealt with throughout the 2012 season.
Kalish underwent two separate surgeries last offseason, both both a bulging disk in his neck and a torn labrum in his shoulder. He didn’t begin participate in minor league games until May 26, ultimately appearing in 36 games with the Red Sox.
The possibility of surgery was first reported by Matthew Stucko of Minor League Baseball’s official Web site (via Twitter).
