The Arizona Cardinals didn't give coach Bruce Arians much to complain about after he watched the tape of their 32-0 rout of the Houston Texans in their preseason opener.

Offensively, he says, there is not much he could say negatively. And on defense, it's hard to criticize a shutout.

It was back to the training camp grind on Monday, with what Arians calls a much tougher challenge next Saturday at Minnesota.

Arians says wide receivers Michael Floyd and Ted Ginn Jr. could miss a second straight game with injuries, Floyd a groin and Ginn a knee.

Several other players sat out Monday's practice, including starting guard Jonathan Cooper (toe) and starting inside linebacker Kevin Minter (pectoral muscles).
