Buffalo Bills Pro Bowl defensive lineman Marcell Dareus failed his conditioning test upon reporting to training camp.

That's why he's on the non-football injury list.

"He's not the only one, but obviously you want your players to come in and be ready to go," coach Doug Marrone told reporters. "We're here for a long period of time and we'll make up for it."

As long as he's on the list, Dareus won't be allowed to practice.

Dareus was arrested twice this offseason.

"He'll be in shape and ready to play," Marrone said. "Right now he needs to focus on getting himself ready, getting himself on the field, and focus on football. I think that's what he'll be ready to do and that's been my conversations with him."
