NEW ORLEANS (AP) - The San Francisco 49ers wrapped up their final practice before the Super Bowl a little early Friday, with a walk-through set for Saturday.

Coach Jim Harbaugh got his team off the indoor field at Saints headquarters 15 minutes early, spending a total of 40 fewer minutes practicing this week than during a regular-season schedule.

The 49ers used crowd noise for offensive and defensive drills because they are playing the Baltimore Ravens on a neutral field Sunday at the Superdome.

Harbaugh said starting linebackers Ahmad Brooks and Aldon Smith - and all others listed on the injury report - would be listed as probable. Brooks and Smith were limited for the third straight day with shoulder injuries.

Punter Andy Lee hit the ceiling several times and then changed his trajectory.
