Brown isn't practicing Wednesday, Jose M. Romero of The Arizona Republic reports.
The Cardinals haven't revealed if Brown is dealing with an injury, but he's coming off a productive outing in this past Sunday's loss to the Bengals, in which he caught four of 10 targets for 61 yards and a touchdown. He's been consistently productive this season, with at least 57 total yards in each game and a touchdown in three of the past four.
