NEW ORLEANS (AP) - The Baltimore Ravens have completed their on-field preparations for the Super Bowl.

Baltimore went through a short walk-through Saturday at the Superdome in front of hundreds of team officials, friends and family. The 15-minute session was more of a pep rally than a workout on the eve of Sunday's championship game against the San Francisco 49ers.

Running back Ray Rice playfully tackled his mother on the sideline and guard Marshal Yanda had a video camera attached to the top of his Ravens cap.

Afterward, coach John Harbaugh described his team's work this week as ``effective.'' He said, ``We've gotten everything we've needed to get done, that's the No. 1 thing.''

The Ravens shared the New Orleans Saints' practice facility with brother Jim and his 49ers on Thursday and Friday.
