IRVING, Texas – Three days after they released two cornerbacks, the Cowboys re-filled their roster by signing two more.

The Cowboys' had two open roster slots after releasing cornerbacks Terrance Mitchell and Brandon McGee on Friday afternoon. On Monday they announced they had addressed those losses by signing corners Isaiah Frey and Dax Swanson.

Both of the new additions come with a bit more experience than the guys they replaced. Frey was a sixth-round pick by the Chicago Bears in 2012, and he spent the better part of three years there. He appeared in all 16 games in 2013, starting six, and recorded 47 tackles.

Upon his release during the 2014 season, he was picked up by Tampa Bay and spent a year with the Buccaneers. Frey spent time on Pittsburgh's practice squad last fall, but he was waived earlier this spring when the Steelers began their offseason program.

Swanson is a local product, coming from Waco, Texas, and playing a chunk of his college career at Sam Houston State. He went undrafted in 2013 and has spent time with six different clubs during his three-year career.

Since 2013, Swanson has spent time with Indianapolis, San Francisco, New England, Tampa Bay, the New York Giants and the Miami Dolphins – primarily as a practice squad player. He was waived by Miami this past February.

The two new additions give the Cowboys a full complement of defensive backs to work with. It's unlikely that veteran corner Orlando Scandrick will do much, if any, competitive work during the upcoming minicamp, which gives an added need for cornerbacks during practice.

The cornerback pecking order looks fairly established heading into training camp, with Scandrick, Brandon Carr and Morris Claiborne all expected to feature prominently. Frey and Swanson should have a chance to compete with the likes of Josh Thomas, Anthony Brown and Deji Olatoye for jobs on the back end of the depth chart.
