New Orleans Saints rookie linebacker Stanley Arnoux ruptured his left Achilles' tendon Friday in the first of five rookie minicamp practices.

The fourth-round pick from Wake Forest will have surgery next week and pending the surgery, a rehabilitation timetable will be announced at a later date. Most Achilles' tendons tears require being sidelined for a full season.

During four seasons at Wake Forest, Arnoux started 42 games. While he played mostly inside linebacker for the Deamon Deacons during his last two seasons, coach Sean Payton said the Saints targeted Arnoux for weakside linebacker, a position Arnoux played his freshman and sophomore seasons.
