Arizona State QB Carpenter questionable for USC

Posted: Updated:

TEMPE, Ariz. (AP) -- Arizona State coach Dennis Erickson says he wants to see how quarterback Rudy Carpenter's sprained left ankle responds before deciding whether he'll play at number 8 USC on Saturday.

Carpenter was hurt in the Sun Devils' 24-14 loss at California last weekend. The senior has made 36 straight starts, but that streak could be in jeopardy.

If Carpenter can't play, the Sun Devils would turn to junior Danny Sullivan, who has completed 1-of-8 passes for minus-1 yard this season.

Erickson says Sullivan would be ready to play if needed.

The Sun Devils have dropped three straight games after opening the season ranked number 15 in The Associated Press Top 25.
