IRVING, Texas -- The Dallas Cowboys have expressed an interest in quarterback Brandon Weeden, according to sources.

The Cleveland Browns released their 2012 first-round pick on Wednesday after he threw 23 touchdown passes and 26 interceptions with a 5-15 record as a starter in two seasons. Weeden, who turns 31 in October, threw for 5,116 yards, completing 438-of-784 passes.

The Cowboys have Kyle Orton as their backup to Tony Romo, and the Cowboys believe he will continue to play rather than retire with a $3.25 million base salary in 2014. If he retires, he would owe the Cowboys $3 million of the $5 million base salary he received in 2012. If he is cut, the Cowboys would save roughly $900,000 in cap space.

Orton turns 32 in November and is in the final year of his contract. After Romo went down in Week 16 with a back injury, Orton came off the bench for the 2013 season finale against the Philadelphia Eagles to throw for 358 yards and two touchdowns in the loss.

Weeden signed a four-year deal worth $8.1 million as the No. 22 pick in the first round two years ago. He is still owed more than $2 million in guaranteed money, but the Browns would only have to make up the difference if Weeden makes less from his new team.

It is possible the Cowboys could carry Romo, Orton and Weeden on the 53-man roster if they were to sign him.

The Cowboys have not carried a third quarterback on the roster since 2011 when they had Stephen McGee behind Romo and Jon Kitna. They had Alex Tanney on the practice squad for much of last season before losing him to the Browns, and re-signed Kitna for the final week of the season after Romo got hurt.

The Cowboys liked Weeden coming out of Oklahoma State. He set school records in yards and touchdowns in 2011 for the Cowboys after a short-lived career in professional baseball.
