Harbaugh brothers share pregame hug

BALTIMORE -- The Harbaugh Bowl started off with John and Jim Harbaugh hugging at midfield during pregame warmups. In case you haven't heard, this is the first time in NFL history that two brothers are going against each other as head coaches.

The brothers then posed with their parents before going to opposite sides of the field. Their parents, Jack and Jackie, are watching the game in a private location at M&T Bank Stadium.

Stay tuned to see what kind of postgame handshake is given. Jim Harbaugh has been known to give an enthusiastic one. Just ask Detroit coach Jim Schwartz.
