Cowboys worst nightmare: Johnson's warming up

Posted by ESPN.com's Matt Mosley
IRVING, Texas -- Tony Romo appeared to get injured when he was sacked by Renaldo Wynn on that last possession. He's limping on the sideline right now and Dr. Dan Cooper's checking him out.

Brad Johnson "fired" some warmup tosses to Brooks Bollinger. A hush has fallen over the stadium. And that's the end of the first quarter. The Cowboys have removed Romo's pads in order to check his back. Dr. Drew Dossett is a renowned back surgeon and he's just joined the medical group surrounding Romo. We'll try to stay on top of it.
