Harris, a freshman who played quarterback at Crenshaw High, caught three passes for 30 yards, including one for 21 yards, in the Trojans' 35-10 victory over Oregon State. He also attempted a pass.
"Not ideal for a skilled athlete to do that, Sarkisian said, "so we'll see how he responds. We're hopeful we can get him back."
If Harris cannot play, that would create an opportunity for redshirt freshman Steven Mitchell as the slot receiver.
