VIERA, Fla. -- St. Louis Cardinals manager Mike Matheny has a ruptured disk in his back.

Matheny, a major league catcher from 1994-06, is scheduled to have an epidural injection Monday to reduce inflammation and get a particle off a nerve. If the injection doesn't help alleviate pain, he said surgery would "have to be something we would consider."

Starting his second season as the Cardinals' manager, Matheny has had back issues for several years.

"I've had problems for a long time, off and on," he said Sunday. "I've been on a program to kind of strengthen it, but ... something set it off in a bad direction. I don't know exactly what it was.

Matheny did not travel with the team to Kissimmee on Friday, citing back pain and food poisoning. He returned to manage the Cardinals on Saturday in Jupiter.
