John and Jim Harbaugh hugged at center field Monday night during pregame warmups as the Baltimore Ravens took on the Los Angeles Chargers.

It is the third time the Harbaugh brothers have faced each other as NFL coaches, but the first since Super Bowl 47 in 2013, when the Ravens defeated the San Francisco 49ers 34-31 in New Orleans.

The other regular season game took place on Thanksgiving night in 2011. The Ravens defeated the Niners 16-6 in Baltimore.

Jim Harbaugh left San Francisco after the 2014 season to take over his alma mater, the University of Michigan. Harbaugh coached at Michigan for nine seasons and won the national title last season before being hired by the Chargers.

He said last week that he was grateful for the opportunity to have another match with his brother.

“When I walked off the field at that Super Bowl, I thought, there will be another day. And there wasn’t for years, and it didn’t seem like I would have a chance for another day,” he said. “But by the grace of God I’m back in it and I’m back on a team that has a chance.”

The brothers chatted for a few minutes and posed for photos before returning to their teams.

“I love my brother. And I would give my life for my brother. But I wouldn’t let him win a football game,” Jim Harbaugh told ESPN during a pregame interview. ‘He wouldn’t want it that way. It feels cool and we’re ready for it.”

John Harbaugh said before the game that coaching against his brother is complicated because their teams are sometimes mirror images of each other.

“It’s all the things we like about each other and it’s also all the things we know about each other that we have to overcome in a game like this,” he told ESPN. “He’s a great coach. He’s a great man. He’s a great leader and he has a great football team, so that complicates it.”

Their parents, Jack and Jackie Harbaugh, celebrated their 63rd wedding anniversary on Monday. They attended the first two games between the brothers, but will spend Thanksgiving week in Bradenton, Florida, at their daughter Joanie’s home.
