IRVING, Texas —
Costa was hampered throughout much of training camp by back issues. He returned in time to play the final preseason game, then started the opener and lasted only one series before being sidelined again.
Costa’s return comes with Ryan Cook bothered by a hamstring injury. The Cowboys got Cook from Miami in a trade at the end of the preseason, and he had been the center since the second series against the Giants.
Ratliff hasn’t played yet this season because of a high ankle sprain.
“Getting Jay back is like getting three guys back. In the nickel packages, in the base packages and then teams actually game plan for Jay Ratliff,” Spears said. “It’ll give other guys the opportunity to probably make more plays and have more success because he’s in the game.”
Linebacker Anthony Spencer also was at practice after missing the Cowboys’ 34-18 loss to Chicago because of a strained pectoral.
“It feels good to essentially have all your guys back out there,” Carr said.
Before practice Monday, the Cowboys added running back Lance Dunbar to their 53-man roster from the practice squad. He ran for 105 yards with a 58-yard touchdown in the preseason finale against Miami.
But the speedy Dunbar, an undrafted rookie from North Texas, will be used primarily on special teams. He could have an immediate impact.
“He’s very aggressive and active,” coach Jason Garrett said. “So we want to give him a chance to do that. He’s also done some returning for us as well. So just wherever he’s needed. We’ll give him some work in practice at the different spots and see how he responds.”
