CINCINNATI (AP) - Reds outfielder Ryan Ludwick tore cartilage in his right shoulder while sliding into base during the season opener and will need surgery.

The team didn't project Tuesday how long Ludwick will be out.

Ludwick dislocated his right shoulder on a headfirst slide into third base in the third inning of Cincinnati's 3-1, 13-inning loss to the Los Angeles Angels on Monday. He had an MRI on Tuesday - the team's day off - that detected the torn cartilage.

He's scheduled for surgery on today. The Reds will place him on the 15-day disabled list before playing the Angels.

It's a significant setback for the defending NL Central champions, who relied on Ludwick to pull them through the loss of Joey Votto last season.
