Orioles manager Buck Showalter said Wednesday that Taylor Teagarden has slight tear in a ligament that supports a disk in his back. Showalter said it sounds worse than it really is, but the injury could prevent him from being ready for Opening Day. The 28-year-old is scheduled to receive an epidural on Wednesday and will be shut down for another week. Ronny Paulino and John Hester, both non-roster players, are the favorites to fill in as the O's backup catcher if Teagarden starts the season on the disabled list.
