Dallas quarterback Tony Romo will miss the rest of the season with a small fracture in the same collarbone that previously sidelined him for seven games this year.

Cowboys owner and general manager Jerry Jones said on his radio show Friday that Romo's left collarbone would not require surgery after getting hurt in the third quarter of Thursday's 33-14 loss to Carolina. He didn't need surgery after breaking the collarbone in Week 2 at Philadelphia, either.

It's the third fracture in Romo's non-throwing shoulder in his nine-year career as the Dallas starter. He missed most of 2010 after getting hurt against the New York Giants.

Romo was in his second game back after the Cowboys (3-8) lost seven straight without him. The Carolina loss was his first of the season.
