JUPITER, Fla. (AP) — Cardinals manager Mike Matheny returned to the club Thursday after undergoing back surgery Monday in St. Louis.

Matheny dealt with severe pain for several days stemming from a ruptured disc in his back that caused particles to come on contact with a nerve. Surgeons found and removed four particles during the 90-minute procedure, known as a microdiscectomy.

The second-year Cardinals manager missed games on Monday and Tuesday before returning Wednesday evening.

Matheny doesn’t expect to miss any additional time but said he was told not to lift anything heavier than five pounds for the next eight weeks. It’s unclear whether or not he’ll be able to throw batting practice in the near future.
