Update on Christian McCaffrey to come this week, says David Shaw

STANFORD, Calif. -- Stanford's Christian McCaffrey suffered an injury during the second half of the Cardinal's 42-16 loss toWashington Stateon Saturday night, but coach David Shaw said an update on his running back's status wouldn't come until this week.

"McCaffrey did get banged up," Shaw said. "But there was no reason to put him in late in the game. We just left him out. We'll see how he is during the course of the week."

McCaffrey left for the locker room in the second half but jogged back onto the field without a limp shortly thereafter. He stretched and jogged in place on the Stanford sideline with his helmet on, but the running back never re-entered the game.
