Predator linebacker Christian Rector will miss multiple weeks of action because of a broken hand which requires surgery. Here’s the USC injury report from Oct. 26.

The hand injury which Christian Rector sustained on Wednesday is serious, and will keep him out for weeks, head coach Clay Helton said on Thursday.

Rector suffered a broken hand and will have to undergo surgery to repair it. Helton described the timetable for his return after surgery as “weeks.”

That is the second major injury the Trojans have dealt with at the predator linebacker position, where Rector was standing in for Porter Gustin, who broke his toe and tore a bicep in September.

Gustin has made progress on a return this week, running for the first time and getting in “limited” work on Thursday. He was described as a “gametime decision” for Saturday but would likely be limited to 15-20 plays even if he suits up.

Oluwole Betiku and Connor Murphy could also see time as options on power formations against ASU.

In addition to the glimmer of hope for Gustin, nose tackle Josh Fatu was also able to move around some on Thursday, according to Helton. He is now a gametime decision as he works to return from a concussion stemming from a car accident last week.

The Trojans will almost certainly be without freshmen Stephen Carr and Josh Falo, however, The running back is still a week away from returning from a foot injury while Falo was in a walking boot on Wednesday and is not expected to be ready for Saturday.

Cornerback Iman Marshall is also sidelined by a sprained MCL.
