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.
