The Dallas Cowboys are expected to look internally to fill the void left by nose tackle Stephen Paea, who decided to retire Wednesday because a knee injury prevented him from playing up to his standards.
That decision leaves the Cowboys with only Maliek Collins and Brian Price as true interior defensive linemen on the roster. David Irving has shown his versatility and got several reps at nose tackle against the Green Bay Packers on Sunday.
But the Cowboys will likely add defensive tackle depth and the internal candidates are practice squad members Lewis Neal and Richard Ash.
