Colorado Rockies shortstop Troy Tulowitzki has been diagnosed with Baseball Pitcher/Hockey Goalie Syndrome and will undergo surgery to repair the injury on Thursday, as the team announced on Wednesday. The Rockies note that a time table won't be set for his return until after the surgery is completed in Philadelphia by Dr. William Meyers.
Here's a small detail from the team regarding the injury:

This certainly doesn't appear to be a common injury, but it's apparently serious enough that surgery is necessary. With Tulowitzki effectively out indefinitely, the Rockies presumably will continue to trot Marco Scutaro out at shortstop for the near future.
