USC's defense has not given up a touchdown pass this season.
That distinction could be tested Saturday when the Trojans face Arizona State quarterback Mike Bercovici, who will start again in place of injured Taylor Kelly.
Bercovici completed 42 of 68 passes for 488 yards and three touchdowns, with two interceptions, in last week's 62-27 loss to UCLA.
USC has intercepted seven passes, including two last week in its 35-10 victory over Oregon State.
Sophomore Su'a Cravens, who moved from safety to linebacker, returned one interception 31 yards for a touchdown. Sophomore safety Leon McQuay III also intercepted a pass that was tipped by freshman cornerback Adoree' Jackson.
Linebackers Anthony Sarao and Michael Hutchings, safety Gerald Bowman, cornerback Chris Hawkins and lineman Leonard Williams also have intercepted passes.
