Cardinals running back Adrian Peterson will not play Sunday.

Adrian Peterson will miss another game.

After not practicing for a second straight week, Peterson (neck) not surprisingly has been ruled out for Sunday against Tennessee. Coach Bruce Arians reiterated there is no timeline for Peterson's return.

"He's walking around fine," Arians said. "It's a matter of taking a hit, and getting all his strength back."

Kerwynn Williams will again start in Peterson's place. Williams had 97 yards last week playing with bad ribs.

"Kerwynn's like the Energizer Bunny," Arians said. "He never slows down."

Wide receiver John Brown (toe) has also been ruled out.

Williams will be helped with left tackle Jared Veldheer in the lineup. Officially, Veldheer (elbow) is listed as questionable, but he returned to practice Friday and Arians said he did well and that Veldheer should be available.

"The strength is back in his arm," Arians said.

Cornerback Patrick Peterson (hamstring) said he is a "little sore," but that he will play against the Titans. Joining Peterson and Veldheer as questionable are defensive lineman Corey Peters (ankle), wide receiver J.J. Nelson (knee) and defensive lineman Josh Mauro (ankle).

Titans linebacker Derrick Morgan (knee) is out for Sunday, the only Tennessee player listed on the final report but a key missing piece for the Titans' pass rush.
