TEMPE, Ariz. (AP) -- Arizona's Beanie Wells went through a limited workout Wednesday and coach Ken Whisenhunt says the team will "really test" the running back's injured knee on Thursday.

That could lead to a full practice Friday and make Wells available to play in Sunday's game at Atlanta.

Wells did not practice all last week and sat out the season opener at St. Louis with a bruised right knee.

Meanwhile, Arizona receiver Early Doucet was being examined for a sports hernia. If that's the case, he will have it repaired, Whisenhunt said, and would be sidelined for "a couple of weeks."

Wide receiver Larry Fitzgerald again went through a full practice with a brace on his sprained right knee. Fitzgerald was noticeably slowed by the injury against the Rams, but says he expects to be improved against the Falcons.
