The Cowboys quarterback, who will replace the injured Tony Romo on Sunday, has been a starting quarterback for the Bears and Broncos during his nine-year career. In fact, Orton has started at least 13 games in four seasons, the last one coming in 2010 with Denver.

Orton, 31, is infamous for having been supplanted as the Broncos' starting QB in 2011 by Tim Tebow, who led Denver to the playoffs that year but has played little since and was unsigned this season.
