Daniels completed 25 of 34 passes for 215 yards in the first half. He tossed his first touchdown of the season on the Trojans' opening drive in the first quarter.
True freshman Kedon Slovis took over for Daniels to start the second half in Los Angeles.
Daniels was later shown on the sidelines in crutches and with a brace.
