Defensive tackle Rob Meier and offensive tackle Richard Collier signed extensions last week.
McDaniel, a 6-foot-7, 310-pound backup entering his third season, is expected to play a more significant role this fall with the departure of Marcus Stroud and Grady Jackson.
McDaniel has 25 tackles and a sack the last two years. He missed the final 12 games last season after suffering a wrist injury.
Details of McDaniel's new contract were not released.
