IRVING, Texas - The Cowboys have placed cornerback Orlando Scandrick on season-ending injured reserve following surgery for torn ligaments in his right knee amid moves to get down to 75 players.

Offensive lineman Chaz Green and linebacker Mark Nzeocha, a pair of injured 2015 draft picks, will miss at least the first six weeks of the season after moving to reserved lists Tuesday. Green, a third-round pick, had off-season hip surgery. Nzeocha, a seventh-rounder, is recovering from a knee injury in college.

The Cowboys waived three players with injury designations: defensive Kenneth Boatright (neck), running back Michael Hill (concussion) and tackle R.J. Dill, who faces a four-game suspension for violating the NFL's substance-abuse policy.

Dallas also waived tight end Brandon Barden, linebacker Jonathan Brown and receivers Antwan Goodley and David Porter.
