The Dallas Cowboys announced Friday that they have signed offensive tackle Pat McQuistan. McQuistan, 29, was Dallas’ seventh-round pick in 2006.

A Cowboy from the day he was drafted through 2009, McQuistan stands 6-foot-6, 319 and has experience at both guard and tackle. He’ll be primarily a tackle in Dallas, competing for a roster spot behind Tyron Smith and Doug Free.

McQuistan bounced from the Dolphins to Saints over the past two seasons.

In a corresponding move, the Cowboys waived undrafted rookie tackle Taylor Dever.
