Cardinals vs. Raiders: Sean Weatherspoon out for Sunday, many game-time decisions

The Arizona Cardinals are set to head to Oakland to play their third preseason game, but first on the road. Head coach Bruce Arians updated the media on Friday before the team's final practice about the injury status of his players. Several players will not travel with the team, while others will be game-time decisions.

Two players are obviously not ready to go -- receiver Michael Floyd, who is recovering from surgery to repair dislocated fingers, and guard Mike Iupati, who had knee surgery. Their status for the season opener is up in the air.

Also out for Sunday's game are tackle Rob Crisp (knee), tight end Troy Niklas (hamstring), cornerback Ross Weaver (unknown), defensive lineman Ed Stinson (toe) and linebacker Sean Weatherspoon (hamstring).

The rest, he said, are decisions to be made on Sunday as to whether they play.

Those players are running back Chris Johnson (hamstring), tight end Jermaine Gresham (recovering from back surgery) and defensive lineman Xavier Williams (elbow).

Cornerback Jerraud Powers is good to go after sitting out several days with a hamstring injury. He returned to practice on Friday and had two interceptions.

As for Chris Johnson, he wants to play some.

"Yeah, he feels pretty good," Arians said. "He's going to try it pregame and he wants to play, so if you want to play, that's a big part of it."
