Chargers vs. Baltimore Ravens: Live updates, kickoff time and odds

As their sons add another chapter to their unparalleled slice of NFL history, Jack and Jackie Harbaugh will be tuning in from across the country.

The warm and endlessly enthusiastic couple will celebrate their 63rd anniversary Monday when sons John and Jim practice against each other for the third time, with Jim’s Chargers hosting John’s Baltimore Ravens at SoFi Stadium.

The Harbaughs are the only brothers to face each other as NFL head coaches. John is 2-0 in matchups, having defeated Jim’s San Francisco 49ers on Thanksgiving in 2011 and by three points in the Super Bowl the following season.
