JUPITER, Fla. - Cardinals manager Mike Matheny will return to St. Louis to have a procedure done on his ailing back Monday.
General manager John Mozeliak confirmed the news Saturday night.
Matheny, who has dealt with severe back pain for several days, will fly to St. Louis following Sunday's exhibition game against the New York Mets and have surgery Monday morning. He's expected to miss Monday and Tuesday's games but return to Jupiter during an off day on Wednesday.
MLB.com reported that Matheny will have a procedure known as a microdiscectomy to remove a participle that came in contact with a nerve following a ruptured disc.
Matheny told reporters Saturday that an epidural shot given last Monday to relieve the pain had worn off. The issue first came public when he didn't travel with the team to a game on March 1 in Kissimmee.
Bench coach Mike Aldrete will serve as the acting manager until Matheny returns.
