Saints top pick injured

(AP) — New Orleans Saints defensive tackle and first-round draft choice Sheldon Rankins suffered a broken fibula during practice on Monday. That’s according to a person familiar with the situation who also tells The Associated Press that Rankins is seeking a second opinion but appears to need surgery.

Typically, fractured fibulas are not season-ending but sideline players for around six weeks.

Rankins was taken 12th overall in this year’s draft.
