Stafford was a limited practice participant Wednesday due to a back injury, Dave Birkett of the Detroit Free Press reports.
With no reports indicating Stafford's back issue is a concern, he should be able to play Sunday in Arizona, flanked by a depleted supporting cast that also includes wideouts Kenny Golladay (quad) and Bruce Ellington (back), who were also limited Wednesday. The Cardinals have allowed just 7.2 yards per pass attempt and 1.4 passing scores per game, typically getting gouged on the ground instead.
