Baltimore Ravens coach John Harbaugh acknowledged Friday that the Ravens and the San Francisco 49ers will conduct four joint practices after their preseason opener. This arrangement makes a lot of sense for both teams, and that's why it isn't out of the question to think this could become an annual family reunion with the Harbaugh brothers. The ideal situation is the Ravens and 49ers holding combined practices with their NFL neighbors. But the Ravens and Washington Redskins haven't arranged an informal scrimmage since 2007, perhaps because of their battle over territorial lines and fans in Maryland.via - NFL Nation
