Saints rookie CB Patrick injured

Saints rookie cornerback Johnny Patrick has left New Orleans' preseason opener against San Francisco with an apparent knee injury.

Trainers were looking at Patrick's right knee behind the Saints' bench during the second half of Friday night's exhibition game before the former Louisville standout was taken from the sideline on a cart.

Patrick, selected with one of the Saints' two third-round picks last April, was credited with three tackles in his pro debut.

Saints officials did not provide immediate word on Patrick's condition.
