On a third-and-1 run, Jake Locker bulled for as many yards as he could near the USC goal-line, even twisted to get a few inches.
And USC's Shareece Wright met him with an inadvertent knee to the head of Locker, and the UW quarterback stayed down for minutes.
Eventually he was helped off the field at the 14:10 mark of the final quarter.
Keith Price came in to throw a 1-yard touchdown to tight end Chris Izbick. UW lead 29-28. It was his second career completion.
