SAN FRANCISCO — Jim and John Harbaugh typically speak on the phone once a week to rehash their respective games. Sometimes it's Sunday night, or perhaps Monday and occasionally even Tuesday.

Jim is unsure when that conversation might take place after John's Baltimore Ravens snapped San Francisco's eight-game winning streak with a 16-6 victory Thursday night, saying, "I don't have a plan."

The game marked the first time in NFL history siblings opposed each other as head coaches.

There are more pressing matters at the moment than friendly family chats. Such as figuring out what happened with an overmatched offensive line that allowed nine sacks of Alex Smith. The 49ers made their share of mistakes to miss key opportunities.

Harbaugh insists his team (9-2) will learn from it.
