Pirates' Cody Bolton: Out with knee injury

Double-A Altoona manager Miguel Perez said Bolton is facing a "long-term" absence after suffering a knee injury during a recent workout, Mike Persak of the Pittsburgh Post-Gazette reports.

The minor-league season started this week, but the right-hander will open the campaign on the injured list with the knee issue. Bolton should be considered out indefinitely until more information is available on the injury.
