Cardinals starters will not practice this week, ruled out for Thursday

The preseason is over for Carson Palmer, Larry Fitzgerald and the rest of the starters.

Head coach Bruce Arians acknowledged they will not play at Denver on Thursday, nor will they practice this week.

The offensive line, however, is still undecided, particularly the center position. It's still a three-man competition between A.Q. Shipley, Lyle Sendlein and Anthony Steen.

Chris Johnson, who signed with the team more than two weeks ago, could make his Cardinals debut.

Johnson has had limited practice time because of a hamstring injury that also forced him to miss the last two preseason games.
