Reported earlier as a simple lower back strain, Galvis suffered a pars fracture in the fifth inning of Wednesday's matchup against the Dodgers when he fouled off a pitch from Chris Capuano. The rookie was in visible pain running down the first base line and left the game after seeing two more pitches.
Added to the 15-day DL after the game, Galvis may have to spend up to six weeks in a brace to allow the vertebra to heal properly. Mike Fontenot and Michael Martinez will likely split playing time at second base in Galvis' absence.
Filling in for the injured Chase Utley, the 22-year-old Galvis has not by any means set the world on fire offensively, hitting just .226/.254/.363 in 58 games. While the offensive numbers are not there, Venezuelan has played above average defense in his short stint with the club.
