TUCSON, Ariz. (AP) - No. 18 Oklahoma State didn't get much of a test in its opener.

The Cowboys' second game figures to be a better gauge of how good they can be.

A week after running over Savannah State 84-0, Oklahoma State heads to the desert on Saturday to play Arizona.

The Cowboys didn't face much resistance in their most lopsided game since World War I, but figure to get more of a challenge from the Wildcats.

Arizona opened the season with a 24-17 overtime win over Toledo. The Wildcats rolled up 624 yards of offense, second-most in school history, but had three turnovers, two touchdowns called back by penalties and two missed field goals.
