The Reds have released this statement:
LF Ryan Ludwick will have surgery tomorrow to repair torn cartilage in his right shoulder. He will go on the 15-day disabled list, and a corresponding roster move will be made prior to tomorrow nightÃ¢â‚¬â„¢s game.
No mention of how long he’s expected to be out.
Lance McAlister is saying that John Fay is predicting either Denis Phipps or Derrick Robinson will be called up.
