Los Angeles Chargers head coach Jim Harbaugh and Baltimore Ravens head coach John Harbaugh are brothers (if you didn't know that, here's a quick rundown of their history), and on Monday, Jim's Chargers play John's Ravens.

Even though John and Jim Harbaugh are coaching against each other on Monday night, their parents won't be in attendance.

For the Baltimore and Los Angeles coaches, the "Monday Night Football" matchup marks their first matchup since Super Bowl XLVII.
