First place in the Pac-12 South is on the line as 22) Arizona visits 17) USC at the L.A. Coliseum on Saturday night.
It's been an incredible four week run for the Wildcats and quarterback Khalil Tate, who has become the first player to win Pac-12 offensive player of the week four straight times. The Wildcat sophomore will be playing in front of friends and family where he made his first collegiate start last season.
"It's a big game," said Tate. "I'm going to do what I've been doing. Just playing my game and letting things come. Whatever happens, happens."
Tate has rushed for 840 yards in the four victories, and he's had a rush of at least 70 or more yards in each of the games.
"We've had more explosive plays in this four game stretch than I can remember, which is a good thing," Arizona head coach Rich Rodriguez said during his weekly press conference.
Arizona senior running back Nick Wilson is listed as probable with an ankle injury after missing last week's 58-37 win over Washington State.
USC has won four straight games over the Wildcats.
