Kinta completed six of 10 passes for 87 yards with the two interceptions and one touchdown.
Now it's been revealed that Romo also suffered a punctured lung in the 49ers game, raising questions about his ability to play in Monday night's home opener vs. the Washington Redskins.
If Romo has struggles with his health, Kinta will be asked to take over, again. Last season, Kitna went 4-5 when Romo was out with a broken collarbone.
"I thought Jon did a really good job in the game," Jason Garrett said. "He came in and I thought he played very comfortably. A couple of times he was aggressive with throws, I take some responsibility for that and sometimes you have to make sure you're calling stuff that helps him get settled into the game. I think I could have done a better job of that, but he came in there and played with confidence."
