It’s a good thing John and Jim Harbaugh are brothers, because they will be sharing a practice facility leading up to Super Bowl XVLII.

The Baltimore Ravens were practicing at Tulane University and complained about the artificial turf being too hard. The Ravens were going through a walkthrough when players noticed the hard surface of the field. After the workout they boarded buses to head to the Saints practice facility eight miles away where the San Francisco 49ers are practicing.

According to a pool reporter at the practice facility, the NFL football operations staff used piping drapes to cover up windows in the weight room to separate the players. They also made sure neither team will be able to watch each others practice on Thursday.

It is fitting that John and Jim are not only sharing the spotlight on the NFL’s biggest stage, but also sharing practice facilities. Had the head coaches sharing the same practice facility the week of the Super Bowl not been brothers, I would scream conspiracy ala Spy Gate. But that’s not the way Jack and Jackie Harbaugh raised their boys. Plus, you don’t win bragging rights in the family by cheating.

The 49ers held practice outdoor and indoor for an hour and 40 minutes. When San Francisco practiced indoors they simulated crowd noise that is expected inside the Superdome on Sunday. On the injury report, Aldon Smith and Ahmad Brooks were both limited at practice with shoulder injuries. But you know Smith and Brooks will be healthy enough to play on Super Sunday. It would take a devastating injury to keep either one out of the game.
