San Francisco Giants backup catcher Tom Murphy will get an injection for a herniated disk in his back that will sideline him for at least two weeks, and could keep him from being ready for the start of the season.

Backup catcher Tom Murphy is likely to miss Opening Day for the San Francisco Giants with a herniated disk in his back. Murphy, 33, had been sidelined with an oblique injury since the first week of spring training for which he got a second opinion late last week.
