What else is Tyron and Jerry going to say right after a game so as to not give the opponent an advantage in preparing? If you look deeper to what beat writers are saying on twitter, they are not quite as confident. A soft tissue injury to groin is not easy to return from in a week.
No real news in dallas news article (Not allowed to post) but definitely a different vibe from headline of "Smith could miss game with strained groin."
We may not know anything for sure until game time approaches. Tyron said he's fine and the reason he left the field was merely precautionary. That doesn't sound like anyone who isn't likely to play. There's a great difference between a tear and a slight strain. We'll know for sure at or around game time.
If Green must take his place, so be it. He does very well if and when he's healthy. If so, there's no doubt that he'll do his best. It'd be a step down for sure but not any worse than if Tyron played injured. Whatever happens, the opposition will prepare as if Tyron will play, whether he actually does or not.
