The Eagles declared reserve running back Chris Polk (shoulder) out of Sunday’s game vs. Dallas, the club said Saturday.
With Polk to miss the game, the Eagles have brought up Matthew Tucker from their practice squad, the club announced.
In a corresponding roster move, the Eagles waived rookie cornerback Jordan Poyer.
Tucker, 22, rushed for 89 yards on 25 carries in the preseason for Philadelphia. He could serve as the third-string tailback behind LeSean McCoy and Bryce Brown on Sunday.
