Running back Joey Iosefa and defensive tackle Kennedy Tulimasealii are on the 64-player travel roster for Saturday's road game against Oregon State.
Both did not play in the USC game while recovering from injuries.
Dejon Allen, who moved from defensive tackle to the offensive line, also is on the travel roster.
Of note, the Rainbow Warriors will take four quarterbacks (Ikaika Woolsey is traveling primarily as a holder) and two kickers (Joe Uglietto is insurance for Tyler Hadden).
The Warriors depart this afternoon.
