The Buffalo Bills have gained one starting defender that was not expected to participate in Sunday evening's opening practice of training camp, but appear to have lost another.
Marcell Dareus was placed on the Active/Non-Football Injury list on Saturday, shortly after the team's conditioning tests concluded. (Reserve offensive lineman J.J. 'Unga was placed on the same list, as well.) It's probably easy to assume that Dareus and 'Unga failed their conditioning tests, but that has not been confirmed, and the Bills did not disclose the reasoning for the move. With Dareus and Alan Branch likely sitting out Sunday night, either Corbin Bryant or Stefan Charles (or both) could see first-team work next to Kyle Williams.
The news is a bit better for cornerback Leodis McKelvin, who was removed from the Active/PUP list just a few days after landing on it. He will participate in Sunday night's opening practice, though he may be on a reduced workload as he continues to work back from offseason hip surgery.
Following these moves, the Bills have six players on non-participation lists as camp begins. Half of them were projected starters less than three weeks ago. Any of these players can be removed from these lists and hit the practice field at a moment's notice (though in the case of Kiko Alonso, two days removed from ACL surgery, that is obviously not likely).
