Marcell Dareus' discouraging offseason continues. Buffalo Bills coach Doug Marrone revealed Sunday that Dareus was placed on the non-football injury list because he failed his conditioning test.

"He needs to focus on getting himself ready," Marrone said according to NFL Media's Albert Breer.

It's unclear when Dareus will be in shape enough to practice. And it's unclear if the NFL will allow Dareus to suit up early in the season.
