A trio of New Orleans Saints are sidelined to start training camp.
The Saints placed outside linebacker Victor Butler, cornerback Patrick Robnson and safety Roman Harper on the physically unable to perform list.
Butler is expected to miss the entire season. He tore his anterior cruciate ligament in June.
Robinson is dealing with an offseason knee injury, too.
It's unclear why Harper isn't able to practice.
