Tony Romo Out for 4 Weeks.

Dallas Cowboys quarterback Tony Romo has a broken pinkie on his throwing hand and will be out four weeks, a team source told ESPN's Michael Smith.

Romo initially was diagnosed with a pinkie sprain in Sunday's 30-24 overtime loss to the Arizona Cardinals.

Veteran quarterback Brad Johnson, the Cowboys' holder on kicks, is Romo's backup.

The Cowboys have lost two of their last three games after starting the season 3-0.
