Fans at the Friendly Confines might get some protection from falling concrete. The Chicago Cubs are reportedly ready to install protective netting at Wrigley Field, after three cases of concrete dropping from the legendary ballpark's upper deck. The Chicago Tribune and Chicago Sun-Times report the netting would go up as a precaution after engineers finish an inspection. A Cubs spokesman wouldn't say much -- other than that the team will know more when the inspection is done. Nobody has been hurt by the falling chunks. But Chicago Mayor Richard Daley has said he wouldn't hesitate to shut down parts or all of the 90-year-old stadium to keep fans safe.
