The possibility of Harrell coming to the Cowboys has been ruled out by a source. Currently, the Cowboys have four quarterbacks on their training camp roster, Tony Romo, Kyle Orton, Nick Stephens and Alex Tanney.
At this stage, the Cowboys seem content to keep just two quarterbacks on the 53-man roster but retaining one for the practice squad is a possibility.
Harrell, who was inducted into the Texas High School Hall of Fame earlier this year, won a Class 4A state title at Ennis in 2001. At Texas Tech, he threw for 15,793 yards with 134 touchdowns and 34 interceptions. In 2008, he won the Johnny Unitas Golden Arm Award.
