Dallas Cowboys All-Pro cornerback Trevon Diggs will be a game-time decision for Sunday’s game against the Atlanta Falcons, head coach Mike McCarthy said on Friday.Diggs has yet to participate in practice this week while dealing with a calf injury sustained in Dallas’ 30-24 setback to the San Francisco 49ers on Sunday. Earlier on Friday, Cowboys owner Jerry Jones said on 105.3 The Fan in Dallas that Diggs has a “tear in his calf.”McCarthy, however, said Diggs had a “good workout” with Cowboys athletic trainer Britt Brown on Friday.”There’s specific drills we’ll need to him to do tomorrow, but he was much better today than we could’ve anticipated,” McCarthy said. “He’s doing everything he can to try to get ready for Sunday.”
