Bruce Arians said the Cardinals will look at their options at wide receiver now that Jaron Brown officially is on injured reserve. Brown was put there today but the Cards did not make a corresponding roster move, meaning they have a slot open. The team did bring back training camp sensation Chris Hubert, who had begun the year on the practice squad, to the practice squad. That gives the Cards two wideouts on the practice squad right now: Hubert and Marquis Bundy.

The Cardinals also worked out veteran wide receiver Aaron Dobson Tuesday, according to Adam Schefter. Dobson, a former second-round pick of New England, has 53 career catches but also had a injury-plagued stint with the Patriots. He spent time with the Lions earlier this season after the Patriots cut him after the preseason.

If everyone currently on the roster is healthy, the Cardinals could get away with not making another receiver the 53rd player on the roster. But that's the question. Michael Floyd should play this week, but he had to play through hamstring issues against the Seahawks. Smokey Brown should be back at practice, but his sickle-cell problem gives at least a little pause. That leaves Larry Fitzgerald, J.J. Nelson and Brittan Golden. Again, if Floyd and Brown are OK, then you're OK. But the Cards might want to cover themselves too.

Bringing up either Bundy or Hubert is also an option. But as the Cardinals get ready to play a Carolina team with a struggling secondary, wide receivers figure to play a big role. The Cardinals want to be in position to use that to their advantage.
