Cowboys S Donovan Wilson sat out Wednesday's practice after aggravating a prior groin injury in the Week 1 loss to Tampa Bay. "It's just not where we thought it would be or hoped it would be," HC Mike McCarthy said, per Michael Gehlken of the Dallas Morning News. "We're just being smart with it. He played a lot of football on Thursday, too." Wilson played 55 of Dallas' 65 defensive snaps (85%) in that game. We'll see about his availability for this Sunday against the Chargers. Jayron Kearse would likely be the fill-in if Wilson can't go.
