John Harbaugh has said that it was tougher than he had expected to defeat his brother Jim Harbaugh in the Super Bowl.
It was the first time that the opposing teams in the Super Bowl have been coached by brothers, with John's Baltimore Ravens beating Jim's San Francisco 49ers 34-31.
The Ravens coach told Sports Illustrated: "I am totally devastated for my brother. It's strange, I don't really feel emotion right now. No tears. I never thought you could feel 100% elation and 100% devastation at the same time. But I learned [on Sunday] you can.
"It's tough. It's very tough. It's a lot tougher than I thought it was going to be. It's very painful."
It is the second time the Baltimore Ravens have won the Super Bowl since the team was founded in 1996.
