Philadelphia Phillies second baseman Freddy Galvis was placed on the 15-day disabled list on Thursday with a lower back strain, but the 22-year-old may have something more serious.
Numerous members of the media are tweeting that the Phillies believe that Galvis has a pars fracture in his back, which he injured swinging in Wednesday night's game.

Kevin Cooney of PhillyBurbs.com is a bit more definitive:
Once Galvis, who is hitting .226 with three home runs and 24 RBIs, gets a second opinion next week, the team will decide on a course of action. A normal course of treatment, according to Wikipedia, does not require surgery but simply involves rest and physical therapy -- which would still keep Galvis out for most if not the rest of the season.
