Tony Romo has begun some light throwing and will return to practice on a limited basis Wednesday. The Cowboys still are formulating a plan for getting Romo back into the mix and readying for a Nov. 22 return to game action, while not interfering with the weekly preparation of Matt Cassel and Brandon Weeden. “We haven’t come up with that plan definitely yet,” Cowboys coach Jason Garrett said Friday. “We talked about some different ideas. Obviously, you want to get him out there doing something. He has been throwing the ball a little bit lately. He looks good that way. Again, you try to ease him back into it without compromising our preparation with the other guys to get ready for the game. We’ll talk about that more specifically as we get closer to it.” Romo fractured his left collarbone in the Week 2 game against the Eagles. The Cowboys placed him on injured reserve designated for return. NFL rules allow him to return to practice next week, but he will miss at least three more games.
